Physics of Ridge and Hard Processes in Proton--Lead and Lead--Lead Collisions with ATLAS

lead-lead collisions with the ATLAS detector

Differential measurements of charged particle azimuthal anisotropy are presented for lead-lead collisions at √ sNN = 2.76 TeV with the ATLAS detector at the LHC, based on an integrated luminosity of approximately 8 μb−1. This anisotropy is characterized via a Fourier expansion of the distribution of charged particles in azimuthal angle relative to the reaction plane, with the coefficients vn de...

HYPERON PRODUCTION IN PROTON-LEAD AND LEAD-LEAD COLLISIONS AT 158 GeV/c PER NUCLEON

for the WA97 collaboration) The WA97 experiment studies the production of strange and multistrange particles in Pb{Pb and p{Pb collisions at 158 GeV/c per nucleon. Recent results on and production ratios and transverse mass distributions are reported and compared with those obtained by WA85 and WA94 experiments. A signiicant enhancement of the // ratio has been observed when going from nucleon-...

Centrality and rapidity dependence of inclusive jet production in √sNN=5.02 TeV proton–lead collisions with the ATLAS detector

Article history: Received 12 December 2014 Received in revised form 16 April 2015 Accepted 14 July 2015 Available online 17 July 2015 Editor: D.F. Geesaman Measurements of the centrality and rapidity dependence of inclusive jet production in √sNN = 5.02 TeV proton–lead (p + Pb) collisions and the jet cross-section in √s = 2.76 TeV proton–proton collisions are presented. These quantities are mea...

Assessment of exposure to lead through air and biological monitoring in a lead and zinc mine

 Background and aim: Lead is ubiquitous and one of the earliest metals discovered by the human. This metal is widely used in different industries due to its important physico-chemical properties like softness, high malleability, ductility, low melting point and resistance to corrosion. Lead absorbed in body with several routs and when transfer in blood is primarily in red blood cells. Human exp...
