On the Energy Loss of High Energy Quarks in a Finite-Size Quark-Gluon Plasma

B. G. Zakharov

We study within the light-cone path integral approach the induced gluon emission from a fast quark passing through a finite-size QCD plasma. We show that the leading log approximat…

Goldstone boson-nucleon dynamics: Working group summary and outlook

Ulf-G. Meißner, Greg Smith

We highlight some of the recent results in chiral dynamics for systems with one nucleon/baryon presented at Chiral Dynamics 2000. We outline the most urgent experimental and theore…

Comparison of Pion-Kaon Scattering in SU(3) Chiral Perturbation Theory and Dispersion Relations

B. Ananthanarayan, P. Büttiker

We establish the framework for the comparison of scattering amplitudes from SU(3) chiral perturbation theory with suitable dispersive representations which result from the com…

The S-wave Λπphase shift is not large

Ulf-G. Meißner, José Antonio Oller

We study the strong interaction S-wave Λπphase shift in the region of the Ξmass in the framework of a relativistic chiral unitary approach based on coupled channels. All parameters…

Mapping the proton unintegrated gluon distribution in dijets correlations in real and virtual photoproduction at HERA

A. Szczurek, N. N. Nikolaev, W. Schäfer +1

We discuss how the dijet azimuthal correlations in DIS and real photoproduction at HERA probe the differential (unintegrated) gluon distribution in the proton. We find a strong dep…

Chiral dynamics in the presence of bound states: kaon-nucleon interactions revisited

J. A. Oller, Ulf-G. Meißner

We study the S-wave kaon-nucleon interactions for strangeness S=-1 in a novel relativistic chiral unitary approach based on coupled channels. Dispersion relations are used to perfo…
