Chiral phase transition in hadronic matter: the influence of baryon density
B. L. Ioffe
A qualitative analysis of the chiral phase transition in QCD with two massless quarks and non-zero baryon density is performed. It is assumed that at zero baryonic density, ,…
Comment on "Vector and axial-vector mesons at finite temperature"
M. Dey, V. L. Eletsky, B. L. Ioffe
It is shown, that the correlators of vector and axial-vector currents at finite temperature T in order T^2 reduce to mixing of vacuum VV and AA correlators with universal mixing co…
Recent progress in QCD at low energies
B. L. Ioffe
The recent results in QCD at low energies are reported. The theoretical analysis of hadronic tau-decay is performed in complex q^2-plane. The terms of perturbation theory (PT) up t…
Proton spin content, axial coupling constant and QCD topological susceptibility
B. L. Ioffe, A. Oganesian
The part of the proton spin carried by quarks is calculated in the framework of the QCD sum rules in the external fields. The operators up to dimension 9 are accounte…
Properties of -mesons produced in heavy ion collisions
V. L. Eletsky, B. L. Ioffe, J. I. Kapusta
The mass shift and width broadening of -mesons produced in heavy ion collisions is estimated. It is found that the mass increases by some tens of MeV but the width becomes large…
The Sum Rules for Structure Functions of Polarized Scattering: Theory vs. Experiment
B. L. Ioffe
The determination of twist-4 corrections to the structure functions of polarized scattering by QCD sum rules is reviewed and critically analyzed. It is found that in the ca…
