Andrew COHEN

Boston University


Work Description:

Andrew Cohen has worked on the physics of the baryon asymmetry of the universe, models of electroweak symmetry breaking, and other topics in particle physics. Currently he is using effective field theory tools to understand the nature of spatial dimensions, and employing the results in constructing models of electroweak symmetry breaking, inflation, and flavor physics.

Title of lecture
Basic Cosmology These 3 lectures will provide a brief introduction to several topics in cosmology with relevance to particle physics. The emphasis will be on the standard cosmological framework rather than on the most recent results. The standard Big Bang cosmology will be introduced, followed by a brief discussion of inflation, the Cosmic Microwave Background, dark energy and baryogenesis.





Work Description:

"I am interested in high-energy physics (HEP), cosmology and astrophysics. At the moment I am fascinated by HEP topics in astrophysics, particularly gamma-ray bursts and cosmic rays of all sorts, including neutrinos."

Title of lecture

I shall discuss the various direct and indirect ways of measuring neutrino masses. The treatment of neutrino oscillations in all books and reviews I know happens to be interestingly incorrect: a good basis to understand the subject a bit better. I shall review the current situation on the subject, as well as the current plans for future measurements.

Work Description:

a) theory and phenomenology of confinement-induced effects in jets and related ``collinear-and-infrared-safe'' QCD observables

b) theory of QCD phenomena in hard processes in nuclei and in high energy ion-ion collisions (medium-induced gluon radiation; quenching)

Title of lecture
QCD Phenomenology We will discuss various aspects of Colour Dynamics in hard, not-so-hard and soft QCD processes: the concept of QCD partons and its limitations, multiple hadroproduction in hard collisions, gluon radiation and colour flows, coherent QCD phenomena in jets, non-perturbative (confinement) effects in QCD observables, perturbative and non-perturbative QCD phenomena in a medium (``cold ''nuclear matter, hot quark-gluon plasma)


Ulrich HEINZ

Ohio State University


Work Description:

"I am working on a global dynamical picture which describes the first sets of data collected in Au+Au collisions at the Relativistic Heavy Ion Collider (RHIC) at BNL. Two aspects of the data I find particularly stimulating: the measured hadronic momentum spectra can all be very well described by a hydrodynamic approach, which assumes very early thermalization already after about 0.5fm/c when the energy density in the collision fireball is still much higher than the critical value for a quark-gluon plasma; however, none of the available dynamical models gets the measured Bose-Einstein correlations right. I am trying to understand which QCD processes are able to lead to such rapid thermalization at the beginning, and how we shoul improve our description of the freeze-out process at the end in order to achieve agreement with the correlation data."

Work Description:

Chris Quigg graduated in physics from Yale University in 1966 and received his Ph.D. from Berkeley in 1970 under J. D. Jackson. After four years in the Institute for Theoretical Physics at Stony Brook (State University of New York), he moved to Fermilab, which has been his scientific home ever since. He was for ten years head of Fermilab's Theoretical Physics Department. In 1987 he returned to Berkeley to serve for two years as Deputy Director of the Superconducting Super Collider Central Design Group. He has held numerous visiting appointments in the U.S. and Europe, and has lectured at summer schools around the world.Quigg's research spans many topics in particle physics, from hadron structure through ultrahigh-energy neutrino interactions. His work on electroweak symmetry breaking and supercollider physics highlighted the importance of the 1-TeV scale. He recently organized the 2001 Snowmass Summer Study on the Future of Particle Physics. A second edition of "Gauge Theories" and a popular book on particle physics are in the works.

Title of lecture
Standard Model & Introduction to Field Theory I will cover the basic elements of the standard model of particle physics: quarks, leptons, and the gauge fields of the strong, weak, and electromagnetic interactions. We will focus on ideas, calculation, and comparison with experiment, not formal details and technicalities. We will rely on recent data to draw a detailed portrait of the standard model and to identify goals of future research---both theoretical and experimental. While looking broadly at opportunities over the next decade, we will highlight the search for the nature of electroweak symmetry breaking and the exploration of the 1-TeV scale.

PREVIEW: I will build the Pylos course around my 2000 TASI Lectures, "The Electroweak Theory," http://arxiv.org/abs/hep-ph/0204104.





Work Description:

"My current research interest is how to use the measurements of CP violation and other properties of B decays to provide a check of the Standard Model picture of CP violation, and to probe for physics beyond the Standard Model. I have been associated with the program of the SLAC B factory and its detector BaBar from the inception of the project and have greatly enjoyed my role there as a bridge between theorists and the experiment."

Title of lecture
Flavour Physics What is flavor physics? Why study it?

The flavor sector is the part of the Standard Model that derives from the interplay of quark weak couplings and quark-Higgs couplings. The Standard Model physics of the quark masses and CKM matrix that encodes both these effects will be briefly reviewed. From a theorists perspective, the aim of aim of the game in flavor physics today is to search for places where the Standard Model predictions are clean enough that the effects of physics from beyond the Standard Model could be recognized if indeed they occur. Along the way we also want to refine our knowledge of SM parameters that appear in the CKM matrix. I will discuss the physics of weak decays of quarks. Predictions at the quark level are clean and simple, since leading order weak effects are all we need. However but of course we observe hadrons, not quarks. Hence I will then explore how and when the quark level physics can be studied at the hadron level. In particular we want to look for those places where the (hard-to-calculate) hadronic physics effects can be separated from the calculable quark-level predictions. This will direct our attention to two classes of results, those on rare decays or effects supressed by symmetries in the Standard Model, and those on CP violation in the decays of neutral but flavor non-singlet mesons. I will review this latter topic in some detail, particularly for the case of B decays, which are the topic of current and planned experimental programs. I will also discuss some examples of rare K decays, and the issue of D-mixing, as examples of effects that are supressed in the Standard Model and which hence provide interesting probes for new physics. I will review the tools that, in some cases, allow us to overcome the complications of hadronic physics. These include the use of symmetries, perturbative qcd, heavy quark effective theory, lattice qcd calculations and qcd sum rules. I will discuss the roles each of these techniques, illustrating them in a variety of cases. I will review how models enter calculations that go beyond these techniques, and discuss the issues that arise when we attempt to quantify the uncertainty of model-dependendent predictions.
