ALICE is the heavy-ion experiment at CERN Large Hadron Collider. The continuously took data during first physics campaign of machine from fall 2009 until early 2013, using proton and lead-ion beams. In this paper we describe running environment handling procedures, discuss performance detectors analysis methods for various observables.
The violation of Baryon Number, $\mathcal{B}$, is an essential ingredient for the preferential creation matter over antimatter needed to account observed baryon asymmetry in universe. However, such a process has yet be experimentally observed. HIBEAM/NNBAR %experiment program proposed two-stage experiment at European Spallation Source (ESS) search number violation. will include high-sensitivity searches processes that violate by one or two units: free neutron-antineutron oscillation...
This paper presents the test results of second prototype SAMPA, ASIC designed for upgrade read-out front end electronics ALICE Time Projection Chamber (TPC) and Muon (MCH). SAMPA is made in a 130 nm CMOS technology with 1.25 V nominal voltage supply provides 32 channels, selectable input polarity, three possible combinations shaping time sensitivity. Each channel consists Charge Sensitive Amplifier, semi-Gaussian shaper 10-bit ADC; Digital Signal Processor digital filtering compression...
Several hadronic observables have been studied in central $158A \mathrm{GeV}$ Pb+Pb collisions using data measured by the WA98 experiment at CERN: single ${\ensuremath{\pi}}^{\ensuremath{-}}$ and ${K}^{\ensuremath{-}}$ production, as well two- three-pion interferometry. The Wiedemann-Heinz hydrodynamical model has fitted to pion spectrum, giving an estimate of temperature transverse flow velocity. Bose-Einstein correlations between two identified analyzed a function ${k}_{T},$ different...
It is anticipated that the LHC will deliver Pb+Pb collisions at a minimum bias interaction rate of about 50 kHz after second long shutdown in 2018. This be roughly two orders magnitude greater than current data recording capability ALICE experiment. Therefore major upgrade detector planned for next to enable record full delivered by LHC. A new point-to-point readout system electromagnetic calorimeter (EMCal) has been developed, replace legacy bus, essentially accomplishes this goal, and...
Ultra-peripheral collisions of relativistic heavy ions involve long-ranged electromagnetic interactions at impact parameters too large for hadronic to occur.The nuclear charges are large; with the coherent enhancement, cross sections also large.Many types photonuclear and purely possible.We present here an introduction ultra-peripheral collisions, four most compelling physics topics.This note developed from a discussion workshop on "Electromagnetic Probes Fundamental Physics," in Erice,...
Abstract A large-volume Time Projection Chamber (TPC) is the main tracking and particle identification (PID) detector of ALICE experiment at CERN LHC. PID in TPC performed via specific energy-loss measurements (d E /d x ), which are derived from average pulse-height distribution ionization generated by charged-particle tracks traversing volume. During Runs 1 2, until 2018, gas amplification stage was based on multiwire proportional chambers (MWPC). Signals MWPC show characteristic long...
The sPHENIX Time Projection Chamber Outer Tracker (TPOT) is a Micromegas based detector. It part of the experiment that aims to facilitate calibration Chamber, in particular correction time-averaged and beam-induced distortions electron drift. This paper describes detector mission, setup, construction, installation, commissioning performance during first year data taking.
We present the mini-proceedings of workshop on ``Photoproduction at collider energies: from RHIC and HERA to LHC'' held European Centre for Theoretical Studies in Nuclear Physics Related Areas (ECT*, Trento) January 15 19, 2007. The gathered both theorists experimentalists discuss current status investigations high-energy photon-induced processes different colliders (HERA, RHIC, Tevatron) as well preparations extension these studies LHC. main physics topics covered were: (i) small-$x$ QCD...
Recent theoretical explanations for how hydrodynamic-like flow can build up quickly in small collision systems (hydrodynamization) has led to a microscopic picture of building gluon-dominated phase before chemical equilibrium between quarks and gluons been attained. The goal this contribution Offshell-2021 is explore consequence assuming long-lived phase, which we shall denote gluon plasma (GP). As these consequences are naturally enhanced large systems, assume the extreme scenario GP would...
