Mesons Modeled Using Only Electrons and Positrons with Relativistic Onium Theory Ray Fleming [email protected]
All mesons modeled using only electrons and positrons with relativistic onium theory Ray Fleming [email protected] All mesons were investigated to determine if they can be modeled with the onium model discovered by Milne, Feynman, and Sternglass with only electrons and positrons. They discovered the relativistic positronium solution has the mass of a neutral pion and the relativistic onium mass increases in steps of me/α and me/2α per particle which is consistent with known mass quantization. Any pair of particles or resonances can orbit relativistically and particles and resonances can collocate to form increasingly complex resonances. Pions are positronium, kaons are pionium, D mesons are kaonium, and B mesons are Donium in the onium model. Baryons, which are addressed in another paper, have a non-relativistic nucleon combined with mesons. The results of this meson analysis shows that the compo- sition, charge, and mass of all mesons can be accurately modeled. Of the 220 mesons mod- eled, 170 mass estimates are within 5 MeV/c2 and masses of 111 of 121 D, B, charmonium, and bottomonium mesons are estimated to within 0.2% relative error. Since all mesons can be modeled using only electrons and positrons, quarks and quark theory are unnecessary. 1. Introduction 2. Method This paper is a report on an investigation to find Sternglass and Browne realized that a neutral pion whether mesons can be modeled as combinations of (π0), as a relativistic electron-positron pair, can orbit a only electrons and positrons using onium theory.

The Muon G-2 Discrepancy: Errors Or New Physics?
The muon g-2 discrepancy: errors or new physics? † M. Passera∗, W. J. Marciano and A. Sirlin∗∗ ∗Istituto Nazionale Fisica Nucleare, Sezione di Padova, I-35131, Padova, Italy †Brookhaven National Laboratory, Upton, New York 11973, USA ∗∗Department of Physics, New York University, 10003 New York NY, USA Abstract. After a brief review of the muon g 2 status, we discuss hypothetical errors in the Standard Model prediction that could explain the present discrepancy with the− experimental value. None of them looks likely. In particular, an hypothetical + increase of the hadroproduction cross section in low-energy e e− collisions could bridge the muon g 2 discrepancy, but is shown to be unlikely in view of current experimental error estimates. If, nonetheless, this turns out to− be the explanation of the discrepancy, then the 95% CL upper bound on the Higgs boson mass is reduced to about 130 GeV which, in conjunction with the experimental 114.4 GeV 95% CL lower bound, leaves a narrow window for the mass of this fundamental particle.

Relationship of Pionium Lifetime with Pion Scattering Lengths In
RELATIONSHIP OF PIONIUM LIFETIME WITH PION SCATTERING LENGTHS IN GENERALIZED CHIRAL PERTURBATION THEORY H. SAZDJIAN Groupe de Physique Th´eorique, Institut de Physique Nucl´eaire, Universit´eParis XI, F-91406 Orsay Cedex, France E-mail: [email protected] The pionium lifetime is calculated in the framework of the quasipotential-constraint theory approach, including the sizable electromagnetic corrections. The framework of generalized chiral perturbation theory allows then an analysis of the lifetime value as a function of the ππ S-wave scattering lengths with isospin I = 0, 2, the latter being dependent on the quark condensate value. The DIRAC experiment at CERN is expected to measure the pionium lifetime with a 10% accuracy. The pionium is an atom made of π+π−, which decays under the effect of strong interactions into π0π0. The physical interest of the lifetime is that it gives us information about the ππ scattering lengths. The nonrelativistic formula of the lifetime was first obtained by Deser et al. 1: 0 2 2 1 16π 2∆mπ (a0 − a0) 2 =Γ0 = 2 |ψ+−(0)| , ∆mπ = mπ+ − mπ0 , (1) τ0 9 s mπ+ mπ+ where ψ+−(0) is the wave function of the pionium at the origin (in x-space) 0 2 and a0, a0, the S-wave scattering lengths with isospin 0 and 2, respectively. The evaluation of the relativistic corrections to this formula can be done in a systematic way in the framework of chiral perurbation theory (χPT ) 2, in the presence of electromagnetism 3. There arise essentially two types of correction. arXiv:hep-ph/0012228v1 18 Dec 2000 (i) The pion-photon radiative corrections, which are similar to those met in conventional QED. -
A Pionic Hadron Explains the Muon Magnetic Moment Anomaly
A Pionic Hadron Explains the Muon Magnetic Moment Anomaly Rainer W. Schiel and John P. Ralston Department of Physics and Astronomy University of Kansas, Lawrence, KS 66045 Abstract A significant discrepancy exists between experiment and calcula- tions of the muon’s magnetic moment. We find that standard formu- las for the hadronic vacuum polarization term have overlooked pio- + nic states known to exist. Coulomb binding alone guarantees π π− states that quantum mechanically mix with the ρ meson. A simple 2-state mixing model explains the magnetic moment discrepancy for 2 a mixing angle of order α 10− . The relevant physical state is pre- ∼ + dicted to give a tiny observable bump in the ratio R( s ) of e e− an- nihilation at a low energy not previously searched. The burden of proof is reversed for claims that conventional physics cannot explain the muon’s anomalous moment. 1. Calculations of the muon’s magnetic moment do not currently agree arXiv:0705.0757v2 [hep-ph] 1 Oct 2007 with experiment. The discrepancy is of order three standard deviations and quite important. Among other things, uncertainties of the anomalous moment feed directly to precision tests of the Standard Model, including the Higgs mass, as well as providing primary constraints on new physics such as supersymmetry. In terms of the Land´e g factor, the “anomaly” aµ = ( g 2 )/2 experimentally observed in muons has become the quintessen- tial precision− test of quantum electrodynamics ( QED ).

Immortal Words: the Language and Style of the Contemporary Italian Undead-Romance Novel
Immortal Words: the Language and Style of the Contemporary Italian Undead-Romance Novel by Christina Vani A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Department of Italian Studies University of Toronto © Copyright by Christina Vani 2018 Immortal Words: the Language and Style of the Contemporary Italian Undead-Romance Novel Christina Vani Doctor of Philosophy Department of Italian Studies University of Toronto 2018 Abstract This thesis explores the language and style of six “undead romances” by four contemporary Italian women authors. I begin by defining the undead romance, trace its roots across horror and romance genres, and examine the subgenres under the horror-romance umbrella. The Trilogia di Mirta-Luna by Chiara Palazzolo features a 19-year-old sentient zombie as the protagonist: upon waking from death, Mirta-Luna searches the Subasio region for her love… but also for human flesh. These novels present a unique interpretation of the contemporary “vampire romance” subgenre, as they employ a style influenced by Palazzolo’s American and British literary idols, including Cormac McCarthy’s dialogic style, but they also contain significant lexical traces of the Cannibali and their contemporaries. The final three works from the A cena col vampiro series are Moonlight rainbow by Violet Folgorata, Raining stars by Michaela Dooley, and Porcaccia, un vampiro! by Giusy De Nicolo. The first two are fan-fiction works inspired by Stephenie Meyer’s Twilight Saga, while the last is an original queer vampire romance. These novels exhibit linguistic and stylistic traits in stark contrast with the Trilogia’s, though Porcaccia has more in common with Mirta-Luna than first meets the eye. -

This thesis has not been submitted for any degree or other purposes. I certify that the intellectual content of this thesis is the product of my own work and that all the assistance received in preparing this thesis and sources have been acknowledged. I acknowledge that this thesis has been read and proofread by Dr. Nina Seja.

Newcastle upon Tyne: Cambridge Scholars Publishing, 2019. Abstract This PhD thesis argues that, in the 1950s and 1960s, several Italian experimental writers developed photographic and cinematic modes of writing with the aim to innovate poetic form and content. By adopting an interdisciplinary framework, which intersects literary studies with visual and intermedial studies, this thesis analyses the works of Antonio Porta, Amelia Rosselli, and Edoardo Sanguineti. These authors were particularly sensitive to photographic and cinematic media, which inspired their poetics. Antonio Porta’s poetry, for instance, develops in dialogue with the photographic culture of the time, and makes references to the photographs of crime news. -

By feminization, this dissertation refers both to the gradual assumption of the majority of elementary teaching positions by women and to a transformation in the nature of the position itself. Through an examination of educational periodicals, school records, government inquests, and accounts by teachers and pedagogical theorists, it argues that rather than the unintended consequence of economic constraints or shifting labor patterns, feminization was fundamentally connected to larger processes of centralization and modernization in the Italian school system. Following an introductory chapter outlining the major national, religious, and gender debates of ii the Unification era, the second chapter of the dissertation argues that the figure of the female elementary teacher became embroiled in the contest between local and national interests, furthering the drive toward centralization.
