Formation of antideuterons in heavy ion collisions
B. L. Ioffe, I. A. Shushpanov, K. N. Zyablyuk
The antideuteron production rate at high-energy heavy ions collisions is calculated basing on the concept of anti-d formation by antinucleons which move in the mean field of the fi…
The Structure Functions of Real Photon at Low Virtualities
I. A. Shushpanov
The structure functions F_2 and F_1 of real photon at low virtualities are calculated in the framework of chiral perturbation theory (ChPT) in the zero and first order of ChPT. It…
The Quark and Gluon Condensates and Low-Energy QCD Theorems in a Magnetic Field
N. O. Agasian, I. A. Shushpanov
The low-energy QCD theorems are generalized in the presence of a constant magnetic field H. Two-loop approximation for the vacuum energy density in the framework of the chiral pert…
Chiral Pertubation Theory with lattice regularization
I. A. Shushpanov, A. V. Smilga
We study the structure and perform some explicit calculations for the power ultraviolet divergences and their renormalization in the Chiral Pertubation Theory with lattice regulari…
Quark condensate in a magnetic field
I. A. Shushpanov, A. V. Smilga
We study the dependence of quark condensate on an external magnetic field. For weak fields, it rises linearly with the field. Pion mass and residue are also shifted so that the…
Electromagnetic Form Factors of the Transition
I. A. Shushpanov
Corrections due to gluon condensate to electromagnetic form factors of the transition are calculated by standard QCD sum rules technique. The obtained results are c…
