Measurement of Upsilon(1S) Elliptic Flow at Forward Rapidity in Pb-Pb Collisions at sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The first measurement of the Υð1SÞ elliptic flow coefficient (v2) is performed at forward rapidity (2.5 < y < 4) in Pb–Pb collisions at sNN 1⁄4 5.02 TeV with the ALICE detector at the LHC. The results are obtained with the scalar product method and are reported as a function of transverse momentum (pT ) up to 15 GeV=c in the 5%–60% centrality interval. The measured Upsilon is consistent with 0 and with the small positive values predicted by transport models within uncertainties. The v2 coefficient in 2 < pT < 15 GeV=c is lower than that of inclusive J=ψ mesons in the same pT interval by 2.6 st ...Daha fazlası

Measuring K0K± interactions using Pb–Pb collisions at √sNN = 2.76STeV

KARASU UYSAL, Ayben | ALICE Collaboration

We present the first ever measurements of femtoscopic correlations between the K0 and K± particles. The analysis was performed on the data from Pb–Pb collisions at sNN = 2.76 TeV measured by the ALICE experiment. The observed femtoscopic correlations are consistent with final-state interactions proceeding via the a0(980) resonance. The extracted kaon source radius and correlation strength parameters for K0 K− are found to be equal within the experimental uncertainties to those for K0 K+ . Comparing the S S results of the present study with those from published identical-kaon femtoscopic studie ...Daha fazlası

Two-pion femtoscopy in p-Pb collisions at √sN N = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We report the results of the femtoscopic analysis of pairs of identical pions measured in p-Pb collisions at sNN = 5.02 TeV. Femtoscopic radii are determined as a function of event multiplicity and pair momentum in three spatial dimensions. As in the pp collision system, the analysis is complicated by the presence of sizable background correlation structures in addition to the femtoscopic signal. The radii increase with event multiplicity and decrease with pair transverse momentum. When taken at comparable multiplicity, the radii measured in p-Pb collisions, at high multiplicity and low pair t ...Daha fazlası

Measurement of D+s production and nuclear modification factor in Pb-Pb collisions at √sNN =2.76TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Abstract: The production of prompt D+s mesons was measured for the first time in collisions of heavy nuclei with the ALICE detector at the LHC. The analysis was performed on a data sample of Pb-Pb collisions at a centre-of-mass energy per nucleon pair, √sNN, of 2.76 TeV in two different centrality classes, namely 0–10% and 20–50%. D+s mesons and their antiparticles were reconstructed at mid-rapidity from their hadronic decay channel D+s → φπ+, with φ → K−K+, in the transverse momentum intervals 4 < pT < 12 GeV/c and 6 < pT < 12GeV/c for the 0–10% and 20–50% centrality classes, respectively.

Measurement of the production of charm jets tagged with D0 mesons in pp collisions at √s = 7 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The production of charm jets in proton-proton collisions at a center-of-mass √ energy of s = 7 TeV was measured with the ALICE detector at the CERN Large Hadron Collider. The measurement is based on a data sample corresponding to a total inte- grated luminosity of 6.23nb−1, collected using a minimum-bias trigger. Charm jets are identified by the presence of a D0 meson among their constituents. The D0 mesons are 0−+0 reconstructed from their hadronic decay D →K π . The D -meson tagged jets are reconstructed using tracks of charged particles (track-based jets) with the anti-kT algo- rithm in the ...Daha fazlası

Study of J/ψ azimuthal anisotropy at forward rapidity in Pb-Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The second (v2) and third (v3) flow harmonic coefficients of J/ψ mesons are measured at forward rapidity (2.5 < y < 4.0) in Pb-Pb collisions at √sNN = 5.02 TeV with the ALICE detector at the LHC. Results are obtained with the scalar product method and reported as a function of transverse momentum, pT, for various collision centralities. A positive value of J/ψ v3 is observed with 3.7σ significance. The measurements, compared to those of prompt D0 mesons and charged particles at mid-rapidity, indicate an ordering with vn(J/ψ) < vn(D0) < vn(h±) (n = 2, 3) at low and intermediate pT up to 6GeV/c ...Daha fazlası

Two-particle differential transverse momentum and number density correlations in p-Pb collisions at 5.02 TeV and Pb-Pb collisions at 2.76 TeV at the CERN Large Hadron Collider

KARASU UYSAL, Ayben | ALICE Collaboration

We present measurements of two-particle differential number correlation functions R2 and transverse momen- tum correlation functions P2, obtained from p-Pb collisions at 5.02 TeV and Pb-Pb collisions at 2.76 TeV. The results are obtained by using charged particles in the pseudorapidity range |η| < 1.0 and transverse momentum range 0.2 < pT < 2.0 GeV/c as a function of pair separation in pseudorapidity, |η|, azimuthal angle φ, and for several charged-particle multiplicity classes. Measurements are carried out for like-sign and unlike-sign charged-particle pairs separately and combined to obtain ...Daha fazlası

Jet fragmentation transverse momentum measurements from di-hadron correlations in √s = 7 TeV pp and √sNN = 5.02 TeV p–Pb collisions

KARASU UYSAL, Ayben | ALICE Collaboration

The transverse structure of jets was studied via jet fragmentation transverse momentum (jT) distributions, obtained using two-particle correlations in proton-proton and proton-lead collisions, measured with the ALICE experiment at the LHC. The highest transverse momentum particle in each event is used as the trigger particle and the region 3 < pTt < 15 GeV/c is explored in this study. The measured distributions show a clear narrow Gaussian component and a wide non-Gaussian one. Based on Pythia simulations, the narrow component can be related to non-perturbative hadronization and the wide compo ...Daha fazlası

Measurement of the production of high-pT electrons from heavy-flavour hadron decays in Pb–Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Electrons from heavy-flavour hadron decays (charm and beauty) were measured with the ALICE detector in Pb–Pb collisions at a centre-of-mass of energy √sNN = 2.76 TeV. The transverse momentum (pT) differential production yields at mid-rapidity were used to calculate the nuclear modification factor RAA in the interval 3 < pT < 18 GeV/c. The RAA shows a strong suppression compared to binary scaling of pp collisions at the same energy (up to a factor of 4) in the 10% most central Pb–Pb collisions. There is a centrality trend of suppression, and a weaker suppression (down to a factor of 2) in semi- ...Daha fazlası

Connection Service Providers (CSP) are wishing to increase their Return on Investment (ROI) by utilizing the data assets generated by tracking subscriber behaviors. This results in the ability to apply personalized policies, monitor and control the service traffic to subscribers and gain more revenue through the usage of subscriber data with ad networks. In this paper, a system is proposed to monitor and analyze the Internet access of the subscribers of a regional SP in order to classify the subscribers into interest categories from the Interactive Advertising Bureau (IAB) categories.

Measurement of an Excess in the Yield of J/ψ at Very Low pT in Pb–Pb Collisions at sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We report on the first measurement of an excess in the yield of J=ψ at very low transverse momentum (pT < 0.3 GeV=c) in peripheral hadronic Pb-Pb collisions at sNN 1⁄4 2.76 TeV, performed by ALICE at the CERN LHC. Remarkably, the measured nuclear modification factor of J=ψ in the rapidity range 2.5 < y < 4 reaches about 7 (2) in the pT range 0–0.3 GeV=c in the 70%–90% (50%–70%) centrality class. The J=ψ production cross section associated with the observed excess is obtained under the hypothesis that coherent photoproduction of J=ψ is the underlying physics mechanism. If confirmed, the observa ...Daha fazlası
