Reference Data 139 Outline -1- / Outline of two projects Fundamental Principles Underlying the Hierarchy of Matter: A Comprehensive Experimental Study / • Outline of the Project This five-year project lead by Dr. R. Kato is the collaborative effort of eight laboratories, in which we treat the hierarchy of matter from hadrons to biomolecules with three underlying and interconnected key concepts: interaction, excitation, and heterogeneity. The project consists of experimental research conducted using cutting-edge technologies, including lasers, signal processing and data acquisition, and particle beams at RIKEN RI Beam Factory (RIBF) and RIKEN Rutherford Appleton Laboratory (RAL). • Physical and chemical views of matter lead to major discoveries Although this project is based on the physics and chemistry of non-living systems, we constantly keep all types of matter, including living matter, in our mind. The importance of analyzing matter from physical and chemical points of view was demonstrated in the case of DNA. The Watson-Crick model of DNA was developed based on the X-ray diffraction, which is a physical measurement. The key feature of this model is the hydrogen bonding that occurs between DNA base pairs. Watson and Crick learned about hydrogen bonding in the renowned book “The Nature of the Chemical Bond,” written by their competitor, L. -

E-mail: [email protected] Abstract. In this talk I discuss aspects of hadron physics, which soon are expected to shed new light on the fundamental QCD phenomena. In the analysis of hadron reactions and their propertieds I emphasize similarities to the nuclear many body problem. 1. Introduction The vast majority of nuclear phenomena can be understood using protons and neutrons as elementary constituents and the nonrelativistic interactions among them. On the other hand, Quantum Chromodynamics (QCD), which is the underlying theory of nuclear forces, describes the relativistic quarks and gluons as the fundamental degrees of freedom. -

Phenomenology from the Lattice PoS(Lattice 2010)018 Christopher Sachrajda∗ School of Physics and Astronomy University of Southampton Southampton SO17 1BJ, UK E-mail: [email protected] In recent years the precision of lattice calculations has improved hugely, and the results are mak- ing a very significant impact in particle physics phenomenology. Indeed there is no alternative general method which can be used in the evaluation of nonperturbative strong interaction effects for a wide variety of physical processes. In this talk I discuss a selection of topics in flavour physics, including mature quantities for which lattice calculations have been performedfor a long time (e.g. the determination of the Vus CKM matrix element and BK), quantities which we are now learning to study (e.g. K ππ decays amplitudes and the spectrum and mixing of η η → − ′ mesons) and important phenomenological quantities for which a large amount of experimental data is available but which we do not yet understand how to approach in lattice simulations (e.g. nonleptonic B-decays). The improvement in precision and the extension of the range of processes which can be studied using lattice QCD has to be continuedvigorously if precision flavour physics is to play a complementary role to large P discovery experiments at the LHC in unravelling the ⊥ next level of fundamental physics.

The proposal is twin track: Firstly to deploy a lower risk but mission critical baseline of new GPU aware algorithms that transform the level of locality by factoring the Fermion determinant to change the balance between interconnect speed and computing throughput. Secondly, to combine this with a higher risk, but high potential reward machine learned change of variables to accelerate the sampling and avoid critical slowing down. Expected Results: The Exascale-aware baseline algorithm is estimated to be a factor of ten faster than current algorithms on the DOE Aurora supercomputer at ANL, by evading communication. The machine learned algorithm field transformation can augment this gain further. These improvements will enable science that aligns with major lab priorities: ● Enable theoretical simulations using chiral fermion discretisations to be performed on substantially finer “grids” than ever before, allowing the inclusion of charm quarks and use of larger momenta. -

Available from the National Technical Information Service, U.S. Department of Commerce, 5285 Port Royal Road, Springfield, Virginia 22161. * Ph.D. thesis ii Abstract This thesis consists of two independent parts; development of Cherenkov Ring Imaging Detector (GRID) system and analysis of high-statistics data of strange meson reactions from the LASS spectrometer. Part I: The CIUD system is devoted to charged particle identification in the SLAC Large Detector (SLD) to study e+e- collisions at ,/Z = mzo. By measuring the angles of emission of the Cherenkov photons inside liquid and gaseous radiators, r/K/p separation will be achieved up to N 30 GeV/c. The signals from CRID are read in three coordinates, one of which is measured by charge-division technique. To obtain a N 1% spatial resolution in the charge- division, low-noise CRID preamplifier prototypes were developed and tested re- sulting in < 1000 electrons noise for an average photoelectron signal with 2 x lo5 gain. To help ensure the long-term stability of CRID operation at high efficiency, a comprehensive monitoring and control system was developed. This system contin- uously monitors and/or controls various operating quantities such as temperatures, pressures, and flows, mixing and purity of the various fluids. -

In the current study, we have experimentally and comparatively investigated and compared malignant human cancer cells and tissues before and after irradiating of synchrotron radiation using Hadron spectroscopy, Baryon spectroscopy and Meson spectroscopy. It is clear that malignant human cancer cells and tissues have gradually transformed to benign human cancer cells and tissues under synchrotron radiation with the passing of time (Figures 1-3) [1-198]. It can be concluded that malignant human cancer cells and tissues have gradually transformed to benign human cancer cells and tissues under synchrotron radiation with the passing of time (Figures 1-3) [1- 198].

They are typically composed of thousands of atoms or more. The most common macromolecules in biochemistry are biopolymers (nucleic acids, proteins, carbohydrates and lipids) and large non–polymeric molecules (such as lipids and macrocycles). Synthetic macromolecules include common plastics and synthetic fibers as well as experimental materials such as carbon nanotubes. Parameters such as FT –IR and Raman vibrational wavelengths and intensities for single crystal Nano polypeptide macromolecule are calculated using density functional theory and were compared with empirical results. The investigation about vibrational spectrum of cycle dimers in crystal with carboxyl groups from each molecule of acid was shown that it leads to create Hydrogen bonds for adjacent molecules. The current study aimed to investigate the possibility of simulating the empirical values. Analysis of vibrational spectrum of Nano polypeptide macromolecule is performed based on theoretical simulation and FT–IR empirical spectrum and Raman empirical spectrum using density functional theory in levels of HF/6–31G*, HF/6–31++G**, MP2/6–31G, MP2/6– 31++G**, BLYP/6–31G, BLYP/6–31++G**, B3LYP/6–31G and B3LYP6–31–HEG**. -

Partially Twisted Boundary Conditions in Lattice Simulations

Moro 2, I-00185 Rome, Italy E-mail: [email protected] We use chiral perturbation theory to investigate twisted and partially twisted boundary conditions which allow access to momenta other than integer multiples of2π/L on a lattice with spatial vol- ume L3. For K ππ decayswe show that the breakingof isospin symmetry by the twisted bound- → ary conditions implies that the amplitudes cannot be determined in general. We find numerical evidence for the result that the finite volume effects of the boundary conditions are exponentially suppressed for quantities without final state interactions (meson masses and meson-to-vacuum matrix elements) in a simulation with partial twisting on a sea of Nf = 2 non-perturbatively im- arXiv:hep-lat/0509093v1 22 Sep 2005 proved Wilson quarks.

Node No. 1: Spain-V (Universitat de Valencia` Estudi General [UVEG]) In collaboration with nodes 9 and 11 [19] a detailed comparison between the results of (quenched) 2 Annual Report — Research Activity lattice QCD and the predictions of (quenched) ChPT at NLO has been performed. In particular, two different chiral regimes (p- and ǫ-regimes) have been considered. Volume and quark mass dependence of current correlators has been studied. In the ǫ regime, also the dependence on the topological charge has been investigated. Finally, the leading order LECs F and Σ have been extracted in the two regimes (milestone no.
