The Gluon Exchange Model in proton-nucleus collisions
Marek Jeżabek, Andrzej Rybicki
We apply our recently formulated Gluon Exchange Model (GEM) to baryon production in proton-nucleus reactions involving N>1 proton-nucleon collisions. We propose a description schem…
Solving the puzzle of nuclear stopping power
Marek Jeżabek, Andrzej Rybicki
This paper reviews our recent findings on the dynamics of transport of baryon number in proton-induced reactions at the CERN SPS. These are put in a more general context of the pre…
Baryon number in proton-proton and proton-nucleus high energy collisions
Marek Jeżabek, Andrzej Rybicki
New analyses of baryon spectra in proton-proton and proton-carbon collisions at GeV, made in the framework of two phenomenological models are present…
The Gluon Exchange Model for diffractive and inelastic collisions
Marek Jeżabek, Andrzej Rybicki
We propose a new model for a homogeneous description of hadron-hadron and hadron-nucleus collisions, the Gluon Exchange Model, fundamentally based on color octet (gluon) exchange.…
Determination of V_ub from semileptonic B decays
M. Jezabek, T. Mannel, B. Postler +1
The hadronic mass distribution in semileptonic B-meson decays can be used for extracting the charmless part and thus determining the |V_ub/V_cb| ratio. We take into account first-o…
Polarization in semileptonic B decays
M. Jezabek, P. Urban
The paper gives the polarization of the tau lepton in the semileptonic B decays with respect to the direction of the virtual W boson. The result is given including the nonperturbat…
Polarized Heavy Quarks
M. Jezabek
Polarization studies for heavy quarks can lead to important tests of the Standard Model. Top quark pair production in annihilation is considered near energy threshold. It…
Polarization in Top Quark Pair Production near Threshold
R. Harlander, M. Jeżabek, J. H. Kühn +1
The polarization dependent momentum distributions of top quarks and their decay products are calculated for production at future colliders with polarized beams.…
Polarization in Top Quark Production and Decay near Threshold
R. Harlander, M. Jeżabek, J. H. Kühn +1
Theoretical results are presented for top quarks produced in annihilation of polarized electrons on positrons. Polarization studies for pairs near threshold are free from…
Hadron Radiation in Leptonic Decays
A. H. Hoang, M. Jeżabek, J. H. Kühn +1
The rate for the final state radiation of hadrons in leptonic decays is evaluated, using as input experimental data for in the low energy region. Configu…
Comment on the Average Momentum of Top Quarks in the Threshold Region
M. Jeżabek, J. H. Kühn, T. Teubner
The behavior of the momentum distribution of top quarks in the threshold region is investigated. The qualitative behavior, in particular the dependence of the average momentum on t…
Radiative Corrections to the top quark width
Marek Jeżabek, Johann H. Kühn, Thomas Teubner
Calculations of radiative corrections to the top quark width are reviewed. QCD effects are discussed for systems produced in annihilation near the energy thresh…
The Top Width - Theoretical update
M. Jeżabek, J. H. Kühn
A critical assessment of the available calculations of the top quark width is presented. QCD corrections, the finite mass of the quark and the effect of the width are inclu…
