QGSJET-II: towards reliable description of very high energy hadronic interactions
S. Ostapchenko
Since a number of years the QGSJET model has been successfully used by different groups in the field of high energy cosmic rays. Current work is devoted to the first general update…
Heavy quark and quarkonium production at CERN LEP2: k_T-factorization versus data
A. V. Lipatov, N. P. Zotov
We present calculations of heavy quark and quarkonium production at CERN LEP2 in the k_T-factorization QCD approach. Both direct and resolved photon contribution are taken into acc…
Prospects of mass measurements for neutral MSSM Higgs bosons in the intense-coupling regime at a Linear Collider
E. Boos, V. Bunichev, A. Djouadi +1
We analyze the prospects for detecting the three neutral Higgs bosons of the Minimal Supersymmetric extension of the Standard Model in the intense-coupling regime at e+e- colliders…
An Invariant Charge Model for All q^2>0 in QCD and Gluon Condensate
A. I. Alekseev, B. A. Arbuzov
Under assumption of singular behavior of invariant charge alpha_s(q^2) at q^2 sim 0 and of large q^2 behavior, corresponding to the perturbation theory up to four loops, a procedur…
Physics Interplay of the LHC and the ILC
LC Study Group, G. Weiglein, T. Barklow +120
Physics at the Large Hadron Collider (LHC) and the International e+e- Linear Collider (ILC) will be complementary in many respects, as has been demonstrated at previous generations…
WMAP constraints on SUGRA models with non-universal gaugino masses and prospects for direct detection
G. Belanger, F. Boudjema, A. Cottrant +2
We discuss constraints on supersymmetric models arising from the relic density measurements of WMAP as well as from direct and precision measurements, LEP, b-sgamma, g-2, Bs-mumu.…
Medium-modified fragmentation of b-jets tagged by a leading muon in ultrarelativistic heavy ion collisions
I. P. Lokhtin, L. I. Sarycheva, A. M. Snigirev +1
The possibility to observe the medium-modified fragmentation of hard b-quarks tagged by a leading muon in ultrarelativistic heavy ion collisions is analyzed. We have found that rea…
The Higgs Working Group: Summary Report 2003
K. A. Assamagan, M. Narain, A. Nikitenko +81
Theoretical progress in Higgs boson production and background processes is discussed with particular emphasis on QCD corrections at and beyond next-to-leading order as well as next…
micrOMEGAs: Version 1.3
G. Belanger, F. Boudjema, A. Pukhov +1
We present the latest version of micromegas, a code that calculates the relic density of the lightest supersymmetric particle in the MSSM. All tree-level processes for the annihila…
Pt-imbalance in dimuon+jet production as a signal of partonic energy loss in heavy ion collisions at LHC
I. P. Lokhtin, A. V. Sherstnev, A. M. Snigirev
We consider a hard jet production tagged by a muon pair in ultrarelativistic heavy ion collisions. The process cross section is calculated by the CompHEP Monte-Carlo generator taki…
Double parton correlations versus factorized distributions
V. L. Korotkikh, A. M. Snigirev
Using the generalized Lipatov-Altarelli-Parisi-Dokshitzer equations for the two-parton distribution functions we show numerically that the dynamical correlations contribute to thes…
The rare decay KL -> pi0 mu+ mu- within the SM
Gino Isidori, Christopher Smith, Rene Unterdorfer
We present an updated analysis of the rare decay within the Standard Model. In particular, we present the first complete calculation of the two-photon CP-…
Calorimetric transverse energy-energy correlations as a probe of jet quenching
I. P. Lokhtin, L. I. Sarycheva, A. M. Snigirev
The sensitivity of calorimetric energy-energy correlation function to the medium-induced energy loss of fast partons in high multiplicity heavy ion interactions is demonstrated at…
The longitudinal structure function F_L: perturbative QCD and k_T-factorization versus experimental data at fixed W
A. V. Kotikov, A. V. Lipatov, N. P. Zotov
We use results for the structure functions for a gluon target having nonzero transverse momentum square at order , obtained in our previous paper, to compare with recent…
CompHEP 4.4 - Automatic Computations from Lagrangians to Events
E. Boos, V. Bunichev, M. Dubinin +7
We present a new version of the CompHEP program (version 4.4). We describe shortly new issues implemented in this version, namely, simplification of quark flavor combinatorics for…
Kinematic selection criteria in a new resonance searches: Application to pentaquark states
B. B. Levchenko
In this note I recall some features of two-body decay kinematics which can be effectively applied, in particular, in experimental searches for pentaquark states.
