Kaon Femtoscopy with Lévy-Stable Sources from sNN=200 GeV Au+Au Collisions at RHIC
نویسندگان
چکیده
Femtoscopy has the capacity to probe space-time geometry of particle-emitting source in heavy-ion collisions. In particular, femtoscopy like-sign kaon-pairs may shed light on origin non-Gaussianity spatial emission probability density. The momentum-correlations between are, hence, measured data recorded by STAR experiment, from $\sqrt{s_{_{\rm NN}}} = 200$ GeV $\mathrm{Au}+\mathrm{Au}$ collisions at RHIC, BNL. Preliminary results hint the, possible, existence non-Gaussian, L\'evy-stable sources; and signal likely, presence an anomalous diffusion process; for identically-charged so produced. More statistically significant studies, lower centre-of-mass energies, contribute search critical end point QCD as well.

متن کاملJet 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...
متن کاملPion Interferometry in Auau Collisions at √ S Nn =200 Gev
We present preliminary results from a two-pion intensity interferometry analysis from Au+Au collisions at √ s NN =200 GeV measured in the STAR detector at RHIC. The dependence of the apparent pion source on multiplicity and transverse momentum are discussed and compared with preliminary results from d+Au and p+p collisions at the same beam energy.
متن کاملPolarized proton collisions at 205 GeV at RHIC.
The Brookhaven Relativistic Heavy Ion Collider (RHIC) has been providing collisions of polarized protons at a beam energy of 100 GeV since 2001. Equipped with two full Siberian snakes in each ring, polarization is preserved during acceleration from injection to 100 GeV. However, the intrinsic spin resonances beyond 100 GeV are about a factor of 2 stronger than those below 100 GeV making it impo...
