Fast simulation of flow effects in central and semi-central heavy ion collisions at LHC
The simple method for simulation of ``thermal'' hadron spectra in
ultrarelativistic heavy ion collisions including longitudinal, transverse and
elliptic flow is developed. The model is realized as fast Monte-Carlo event
generator.Comment: 6 pages, LaTe
Probing the medium-induced energy loss of bottom quarks by dimuon production in heavy ion collisions at LHC
The potential of coming experiments on Large Hadron Collider (LHC) to observe
the rescattering and energy loss of heavy quarks in the dense matter created in
heavy ion collisions is discussed. We analyze the sensitivity of high-mass
mu+mu- pairs from BBbar semileptonic decays and secondary J/Psi from single B
decays to the medium-induced bottom quark energy loss.Comment: LaTeX+3 figures, epsfig.st
Nuclear geometry of jet quenching
The most suitable way to study the jet quenching as a function of distance
traversed is varying the impact parameter b of ultrarelativistic
nucleus-nucleus collision (initial energy density in nuclear overlapping zone
is almost independent of b up to b R_A). It is shown that b-dependences of
medium-induced radiative and collisional energy losses of a hard parton jet
propagating through dense QCD-matter are very different. The experimental
verification of this phenomenon could be performed for a jet with non-zero cone
size basing on essential difference between angular distributions of
collisional and radiative energy losses.Comment: LaTeX+7 figures, epsfig.st
