Lifetime estimations from RHIC Au+Au data

Nuclear surface effects in AuAu @ RHIC

Jet Tomography Studies in AuAu Collisions at RHIC Energies

Recent RHIC results on pion production in AuAu collision at √ s = 130 and 200 AGeV display a strong suppression effect at high pT . This suppression can be connected to final state effects, namely jet energy loss induced by the produced dense colored matter. Applying our pQCD-based parton model we perform a quantitative analysis of the measured suppression pattern and determine the opacity of t...

Diffractive J/ψ production in Ultraperipheral AuAu Collisions at RHIC

Estimations of temperature at RHIC experiments

We have systematically estimated the possible temperatures T obtained at RHIC experiments by analyzing recent data on pt distributions provided by them. Different schemes of estimating T are used with special emphasis put on the concept of the possible indication of the temperature fluctuations seen in data. Our analysis suggests that we can choose a correct approach provided that data with lar...

Beam Lifetime Dependence on the Beam-Gas Interactions in RHIC

In the Relativistic Heavy ion Collider (RHIC) much larger background signals were occurring at BRAMS, one of the four experiments. This was especially pronounced at the time when vacuum conditions deteriorated due to the beam ionization profile monitor replacements. Recording the beam intensities during the store provided the beam lifetime. Predictions from the beam gas interactions to the abov...
