Prompt photon hadroproduction in the k_T-factorization approach
S. P. Baranov, A. V. Lipatov, N. P. Zotov
We study the production of prompt photons at high energy in the framework of the k_T-factorization approach. The amplitude for production of a single photon associated with quark p…
Manifestation of three-body forces in three-body Bethe-Salpeter and light-front equations
V. A. Karmanov, P. Maris
Bethe-Salpeter and light-front bound state equations for three scalar particles interacting by scalar exchange-bosons are solved in ladder truncation. In contrast to two-body syste…
Production and polarization of Upsilon mesons in the k_T-factorization approach in more detail
S. P. Baranov, N. P. Zotov
In the framework of the k_T-factorization approach, the production and polarization of Upsilon mesons at the Fermilab Tevatron is considered, and a comparision of the calculated do…
Inflation scenario via the Standard Model Higgs boson and LHC
A. O. Barvinsky, A. Yu. Kamenshchik, A. A. Starobinsky
We consider a quantum corrected inflation scenario driven by a generic GUT or Standard Model type particle model whose scalar field playing the role of an inflaton has a strong non…
Electromagnetic form factor via Bethe-Salpeter amplitude in Minkowski space
J. Carbonell, V. A. Karmanov, M. Mangin-Brinet
For a relativistic system of two scalar particles, we find the Bethe-Salpeter amplitude in Minkowski space and use it to compute the electromagnetic form factor. The comparison wit…
Cherenkov Glue in Opaque Nuclear Medium
I. M. Dremin, M. R. Kirakosyan, A. V. Leonidov +1
The spectrum of Cherenkov gluons is calculated within the framework of in-medium QCD. It is compared with experimental data on the double-humped structure around the away-side jet…
Production of electroweak gauge bosons in off-shell gluon-gluon fusion
S. P. Baranov, A. V. Lipatov, N. P. Zotov
We study the production of electroweak gauge bosons at high energies in the framework of kt-factorization QCD approach. Contributions from the valence quarks are calculated using t…
Associated production of prompt photons and heavy quarks in off-shell gluon-gluon fusion
S. P. Baranov, A. V. Lipatov, N. P. Zotov
In the framework of the kt-factorization approach, we study the production of prompt photons associated with heavy (charm and beauty) quarks in hadron-hadron collisions at high ene…
Comment on "Polarizability of the pion: No conflict between dispersion theory and chiral perturbation theory"
L. V. Fil'kov, V. L. Kashevarov
The statement of the authors of the article Phys. Rev. C 77, 065211 (2008) that spurious singularities occur in the dispersion relation approach, where imaginary parts of the ampli…
In-medium QCD and Cherenkov gluons
I. M. Dremin
The equations of in-medium gluodynamics are proposed. Their classical lowest order solution is explicitly shown for a color charge moving with constant speed. For nuclear permittiv…
