Perspectives in Hadron Physics ICISE, Quy Nhon, Vietnam September 22-28, 2019 Booklet of Abstracts 15th Rencontres du Vietnam Perspectives in Hadron Physics ICISE, Quy Nhon, Vietnam September 22-28, 2019 Booklet of abstracts Version of September 13, 2019 1 1 Kaonic hydrogen and deuterium from SIDDHARTA Claude AMSLER Stefan Meyer Institute for Subatomic Physics, Vienna [email protected] Data on the KN interaction very close to threshold (e.g., from kaonic atoms) pro- vides information on the interplay between spontaneous and explicit chiral symmetry breaking in low energy QCD. Kaonic hydrogen was investigated with unprecedented precision by the SIDDHARTA experiment at the DAφNE electron-positron collider of LNF (Frascati), which delivers very low energy charged kaons from the decay of the φ resonance. The strong interaction shift and broadening of the ground state were mea- − sured, from which the s-wave K p scattering length a = 1=2(a0+a1) was derived, where a0 (a1) are the two isoscalar (isovector) components. To determine the two contributions separately, measurements of the shift and width of the 1s kaonic deuterium atom are re- quired. This is one of the most important missing information on the low-energy KN interaction. The approved experiment SIDDHARTA-2 at LNF intends to measure the transition X-rays to the ground state of kaonic deuterium. Challenging are the very small X-ray yields, the even larger widths compared to hydrogen, and the high radiation environ- ment. Data are not available so far (apart from an exploratory experiment performed at DAφNE in 2013). We are developing large area X-ray detectors by optimizing the signal-over-noise ratio, improving on the timing capability and implementing charge particle tracking and veto devices. Installation of the SIDDHARTA-2 apparatus has started in spring 2019. A data-taking period of about 6 months is planned in 2020. An integrated luminosity of 800 pb−1 is required to reach the goals of 30 eV uncertainty on the 1s level shift and 75 eV on its width. The final results of SIDDHARTA on kaonic hydrogen will be summarized. The physics impact of the kaonic deuterium project will be discussed, and the current status of SIDDHARTA-2 presented. 2 Decoding the phase structure of QCD with high energy nuclear collisions Peter BRAUN-MUNZINGER EMMI/GSI Darmstadt [email protected] In this talk we demonstrate that the phase structure of strongly interacting matter can be decoded via analysis of particle production in high energy nuclear collisions. This is achieved by making use of the observed thermalization pattern of particle abun- dances within the framework of the statistical hadronization approach at various colli- sion energies. The thermalization holds not only for hadronic constituents composed of 1 light quarks but also for light, loosely bound nuclei. The observed energy dependence of the production yields and fluctuations of different particle species contains charac- teristic features which are used to determine the temperature and baryo-chemical po- tential of the matter produced. Furthermore, we demonstrate how charm quarks can be included into the analysis . This can be used to provide information on the degree of deconfinement in the fireball. The above observations imply quark-hadron duality at the QCD phase boundary and establish the first experimental delineation of the location of the phase change in strongly interacting matter. New experimental opportunities for relativistic nuclear collisions are pointed out for the near and longer term future. 3 Structure of the charmed baryons through an electro- magnetic perspective Kadir-Utku CAN RIKEN, Japan [email protected] In this talk, we investigate the electromagnetic properties of the charmed baryons with a focus on our lattice QCD calculations. By comparing the different sectors, such as the spin-1/2 baryons to the spin-3/2 ones or the singly charmed to the doubly charmed baryons, we reveal the inner dynamics and the characteristics of the charmed baryons. We comment on the tension between our lattice determinations and the results obtained via other methods, and discuss the possible reasons. 4 Recent Results from GlueX Mark DALTON Jefferson Lab (For the GlueX Collaboration) [email protected] The GlueX Experiment at Jefferson Lab uses a 9 GeV linearly polarized photon beam incident on a liquid hydrogen target and a solenoidal spectrometer providing nearly complete coverage for charged and neutral particles. GlueX has completed phase 1 of data taking having acquired many orders of magnitude more photo-production data than previously available. The ultimate goal is to search for and map the spectrum of light hybrid mesons. Towards this goal, polarization observables, spin density matrix elements (SDMEs), and cross-sections of mesons are being measured in order to un- derstand their production mechanisms. This talk will discuss the recent results from GlueX. 2 5 Nucleon spin structure from large to small distances Alexandre DEUR Jefferson Lab [email protected] We will summarize the measurements investigating the nucleon longitudinal spin structure. After motivating its study, we will discuss the recent experimental data, in particular that at large distance, and what they teach us. The experimental data have now provided a precise mapping of the nucleon longitudinal spin structure from large to small distances. This achievement went in hand with important theoretical advances such as improvements in Chiral Perturbation Theory, the perspective for lattice QCD to compute structure functions, or the application of Light–Front Holographic QCD to the nucleon spin structure. 6 Hadron structure results from COMPASS and plans for AMBER Celso FRANCO LIP-Lisbon, Portugal [email protected] The COMPASS experiment at CERN is one of the leading experiments studying the proton structure. In what concerns the spin and momentum dependence of the par- ton distribution functions COMPASS has been performing several measurements, since 2002, using the following processes: deep inelastic scattering of polarised muons off lon- gitudinally and transversely polarised NH3 and 6LiD targets and also the pion-induced Drell-Yan reaction in a transversely polarised NH3 target. An overview of the COM- PASS results on this topic will be presented. A proposal for a new CERN experiment on hadron structure and spectroscopy with extended scientific scope with respect to COM- PASS, the AMBER project, will also be discussed. Namely, the planned measurements on the pion and kaon structure will be presented. 7 On non-conformal models for bottom-up holographic QCD Anastasia GOLUBTSOVA Joint Institute for Nuclear Research [email protected] Recent years holographic duality has been tremendously successful in giving deep insights into strongly coupled QCD, in particular physics of quark-gluon plasma. In 3 this talk I will focus on the bottom-up models that can implement holographically the renormalization group flow of QCD at zero and finite temperatures. These models can be studied analytically while having features resembling the real QCD, in particular reproducing the QCD running coupling. I will consider estimations for heavy quark potential and drag force of a moving quark in the holographic backgrounds. The gen- eralization of the models to the case of finite baryonic density will be also discussed. 8 Light-meson spectroscopy at COMPASS Boris GRUBE Technische Universiät München [email protected] The excitation spectrum of light mesons, which are composed of up, down, and strange quarks, is studied since decades. However, it still holds a number of puzzles and surprises that provide new insights into the nature of the strong interaction. Recent high-quality data samples from the COMPASS experiment at CERN allow us to not only study the properties of established mesons with unprecedented precision but to also search for new states. These searches in particular aim to resolve the question of the existence of so-called exotic states, such as four-quark states or states with excited gluon fields. Since light mesons have often large widths and are overlapping, the mapping of their spectrum is challenging and requires large quantities of data. The data are analyzed using a framework of interfering quantum amplitudes known as partial-wave analysis (PWA). Most excited meson states decay into multi-particle final states, for which the PWA requires extensive modeling of the dynamics of the final-state hadrons. In this talk, I will give an overview of the ongoing experimental studies of light mesons at COMPASS. I will also touch on novel analysis techniques and the prospects for future progress. 9 Five–body structure of ssscc¯ system Emiko HIYAMA Kyushu Univ./RIKEN [email protected] We introduce the structure of ssscc¯ system which has never been observed, within the framework of the constituent quark model. Then, we will discuss whether or not we have compact sharp resonant states which are genuine pentaquark systems. 4 10 Pc as heavy hadronic molecules with pion exchange force Atsushi HOSAKA RCNP, Osaka University [email protected] We study recently observed Pcas hadronic molecules, presenting how a simple model with pion exchange force can describe the LHCb data for masses and widths. The role of the tensor force is analyzed, and we discuss its importance in the formation of the molecules. 11 Status of Λ(1405) in chiral dynamics Tetsuo HYODO Tokyo Metropolitan University [email protected] We introduce the current status of the Lambda(1405) resonance in chiral SU(3) dy- namics. Whole set of low-energy experimental data around the K−p threshold, includ- ing the recent precise measurement of the kaonic hydrogen, can be described in the framework of the NLO chiral SU(3) dynamics. We show the determination of the pole structure in the Λ(1405)region, and then discuss the internal structure of the Λ(1405). 12 Study of KN¯ interaction from the hadron-hadron cor- relation in high-energy nuclear collisions Yuki KAMIYA Institute of Theoretical Physics, Beijing [email protected] We discuss the KN¯ correlation in high-energy nuclear collisions and its relation to the KN¯ interaction.

Since the first beam was extracted at the hadron experimental facility (HEF) in February 2009, a wide variety of physics experiments have been proposed and performed to address open questions regarding quantum chromodynamics (QCD) at low energy. The high-intensity K− and high-momentum beams available at J-PARC open a new era in hadron and nuclear physics, in which strange and charm quarks play an important role. We review the programs focused on addressing the hadron structure as strongly interacting composite particles, the origin of hadron mass, and interactions between hadrons under broken flavor SU(3) symmetry.

    Doubly charmed tetraquarks in a diquark-antidiquark model Xiaojun Yan, Bin Zhong and Ruilin Zhu ∗ Department of Physics and Institute of Theoretical Physics, Nanjing Normal University, Nanjing, Jiangsu 210023, China We study the spectra of the doubly charmed tetraquark states in a diquark-antidiquark model. The doubly charmed tetraquark states form an antitriplet and a sextet configurations according to flavor SU(3) symmetry. For the tetraquark state [qq0][¯cc¯], we show the mass for both bound and excited states. The two-body decays of tetraquark states T cc[0+] and T cc[1−−] to charmed mesons have also been studied.

Box MG6, R-76900 Romania (ricevuto il 12 Settembre 1997; approvato l’8 Ottobre 1997) Summary. — The possibility of disentangling for the first time the KFb-complex in kaonic hydrogen is shown to be realistic with the DEAR experiment. A precise identification of the pattern of lines in kaonic hydrogen and in kaonic deuterium can allow to obtain the first experimental determination of the KN sigma terms. PACS 13.75.Jz – Kaon-baryon interactions. PACS 36.10 – Exotic atoms and molecules (containing mesons, muons, and other unusual particles). 1. – Kaonic-hydrogen formation and energy levels An “exotic atom” is formed whenever an electron of an outer orbit of an atom is replaced by a heavier charged particle, such as a muon (m 2), or hadrons like a pion (p 2 ), a kaon (K2 ), an antiproton (p) or a sigma hyperon (S2 ). Among the exotic atoms, the hydrogen-like systems are of particular importance, because they have the simplest structure and are free from any screening effect due to bound electrons. By studying them, one can, for instance, directly probe the hadron-nucleon interaction at zero energy. The case of kaonic hydrogen. The mechanism of formation of a kaonic hydrogen atom is the following: a negative kaon enters into a hydrogen target; it loses its kinetic energy by ionization and excitation of the hydrogen molecules until it is captured into an atomic orbit around the proton (by replacing the electron).
