  • Nucleon Resonances and Quark Structure
    Nucleon Resonances and Quark Structure J.T. Londergan Physics Dept and Nuclear Theory Center, Indiana University, Bloomington, IN 47405, USA. [email protected] (Dated: October 25, 2018) A pedagogical review of the past 50 years of study of resonances, leading to our understanding of the quark content of baryons and mesons. The level of this review is intended for undergraduates or first-year graduate students. Topics covered include: the quark structure of the proton as revealed through deep inelastic scattering; structure functions and what they reveal about proton structure; and prospects for further studies with new and upgraded facilities, particularly a proposed electron- ion collider. Keywords: I. INTRODUCTION These lectures were given at Aligarh Muslim University, Aligarh India, at a nuclear physics workshop attended by Indian graduate students and postdocs. These lectures provide a pedagogical review of the past 50 years of experimental and theoretical studies of the quark and gluon structure of the nucleon. Since many speakers at this workshop will discuss structure functions extracted from deep inelastic scattering reactions, we define these quantities and review what can be extracted from them. We hope that specialists in this field will tolerate our brief and superficial summary of many years' study of strongly-interacting systems. FIG. 1: Richard H. Dalitz, 1925-2006. arXiv:0907.3431v1 [hep-ph] 20 Jul 2009 These lectures are dedicated to my mentor, Richard Dalitz, who was from 1963-2000 Royal Society Professor of Physics at Oxford University and who made seminal contributions in particle phenomenology. Dalitz pairs (electron- positron pairs from decay of a high-energy photon) and the Dalitz plot were named after him.

  • Dalitz Analyses: a Tool for Physics Within and Beyond the Standard
    DCPT/06/112 IPPP/06/56 DALITZ ANALYSES: A TOOL FOR PHYSICS WITHIN AND BEYOND THE STANDARD MODEL M.R. PENNINGTON Institute for Particle Physics Phenomenology, Durham University, Durham DH1 3LE, United Kingdom Abstract Dalitz analyses are introduced as the method for studying hadronic decays. An accurate description of hadron final states is critical not only to an understanding of the strong coupling regime of QCD, but also to the precision extraction of CKM matrix elements. The relation of such final state interactions to scattering processes is discussed. 1 Motivation This serves as the introduction to following talks on Dalitz plot analyses. I will first remind arXiv:hep-ph/0608016v1 2 Aug 2006 you of the motivation for such analyses and discuss some aspects of how to perform them and I leave it to others to describe detailed results. We know that there is physics beyond the Standard Model but we do not yet know what this is. Insight is provided by precision measurements of the CKM matrix elements, and in particular the length of the sides and the angles of the CKM Unitarity triangle. Such measurements in heavy flavour decays probe the structure of the weak interaction at distance scales of 0.01fm. However, the detector centimetres away records mainly pions and kaons as the outcome of a typical process like B → D(→ Kππ)K decay. Consequently, the very short distance interaction we wish to study is only seen through a fog of strong interactions, in which the quarks that are created exchange gluons, bind to form hadrons and then these hadrons interact for times a 100 times longer than the basic weak interaction.

His most well-known contribution is the proposal that protons and neutrons are not indivisible but are made up of smaller particles called ‘quarks’.

Sometime after the discovery of the neutron, the German physi- cist Werner Heisenberg introduced a concept called ‘isospin sym- metry’ to make sense of the fact that they (proton and neutron) are so similar in many respects. This symmetry is now called the ‘SU(2) symmetry’ because it concerns two objects – the pro- ton and the neutron. The mathematical object SU(2) is called a ‘group’. In 1935, the Japanese physicist Hideki Yukawa propounded a now-famous theory that the protons and neutrons were bound to- gether inside the nucleus because they exchanged particles, later Keywords called ‘mesons’. Further studies with cosmic rays confirmed the Quarks, mesons, pions, strong in- existence of these particles.

He was an early proponent of the importance of gauge theories in quantum field theory and their use in showing the renormalisation of those theories: that is to remove apparent infinities in calculations. He showed that gauge invariance implies the equality of two seemingly different renormalised quantities in QED, a relationship now called the Ward Identity.

  • Iterview with Valentine L. Telegdi
    VALENTINE L. TELEGDI (1922 – 2006) INTERVIEWED BY SARA LIPPINCOTT March 4 and 9, 2002 ARCHIVES CALIFORNIA INSTITUTE OF TECHNOLOGY Pasadena, California Subject area Physics Abstract Valentine Louis Telegdi was born in Budapest in 1922 and grew up in Bulgaria. He took his Master of Science degree in chemical engineering at Lausanne University in 1946 and received his PhD in 1950 from the ETH (Eidgenössische Technische Hochschule), the Swiss Federal Institute of Technology. Victor Weisskopf and Gregor Wentzel were instrumental in his appointment as an instructor at the University of Chicago in 1951, where he worked with Murray Gell-Mann. In 1954, after Enrico Fermi’s death, Telegdi became the head of Fermi’s Nuclear Emulsion Group there. In 1956, he went to the Institute for Advanced Study for three months. Later that year, back in Chicago, he and Jerome I. Friedman found parity violation in muon decay, in parallel with the work of Chien-Shiung Wu at Columbia and her collaborators at the National Bureau of Standards, and that of Richard L. Garwin, Leon M. Lederman, and Marcel Weinrich at Columbia. In 1959-1960, on leave from Chicago, Telegdi worked with Garwin at CERN on the anomalous magnetic moment of the muon. In 1966, again on leave from Chicago, he had a visiting lectureship at Harvard. In 1968, Telegdi was elected to the National Academy of Sciences and in 1972 he http://resolver.caltech.edu/CaltechOH:OH_Telegdi_V became the Enrico Fermi Distinguished Service Professor of Physics at Chicago. He left the university four years later—discouraged at what he called the “decay” of the Enrico Fermi Institute since Fermi’s death and the increasingly cumbersome grants process—and returned to Switzerland, where he headed a group at the ETH doing atomic physics; he also took up a joint appointment at CERN, heading a particle physics group.
