Measurement of the Longitudinal Spin Transfer to Lambda and Anti-Lambda Hyperons in Polarised Muon DIS

The COMPASS Collaboration, M. Alekseev

The longitudinal polarisation transfer from muons to lambda and anti-lambda hyperons, D_LL, has been studied in deep inelastic scattering off an unpolarised isoscalar target at the…

A model for net-baryon rapidity distribution

J. Alvarez-Muñiz, R. Conceição, J. Dias de Deus +3

In nuclear collisions, a sizable fraction of the available energy is carried away by baryons. As the baryon number is conserved, the net-baryon retains information on t…

J/psi polarization from fixed-target to collider energies

Pietro Faccioli, Carlos Lourenco, Joao Seixas +1

The determination of the magnitude and "sign" of the J/psi polarization crucially depends on the reference frame used in the analysis of the data and a full understanding of the po…

Phi decay: a relevant source for K- production at SIS energies?

The HADES Collaboration, G. Agakishiev, A. Balanda +110

We present phase space distributions and multiplicities of K+, K- and phi mesons produced in Ar+KCl reactions at a kinetic beam energy of 1.756 AGeV and measured with the HADES spe…

Pattern recognition and PID for COMPASS RICH-1

P. Abbon, M. Alexeev, H. Angerer +65

A package for pattern recognition and PID by COMPASS RICH-1 has been developed and used for the analysis of COMPASS data collected in the years 2002 to 2004, and 2006-2007 with the…

Energy dependence of J/psi absorption in proton-nucleus collisions

Carlos Lourenco, Ramona Vogt, Hermine K. Woehri

Charmonium states are expected to be considerably suppressed in the case of quark-gluon plasma formation in high-energy heavy-ion collisions. However, a robust identification of su…
