Multiplicity dependence of jet-like two-particle correlation structures in p–Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Two-particle angular correlations between unidentified charged trigger and associated particles are measured by the ALICE detector in p–Pb collisions at a nucleon–nucleon centre-of-mass energy of 5.02 TeV. The transverse-momentum range 0.7 < pT,assoc < pT,trig < 5.0 GeV/c is examined, to include correlations induced by jets originating from low momentum-transfer scatterings (minijets). The correlations expressed as associated yield per trigger particle are obtained in the pseudorapidity range |η| < 0.9. The near-side long-range pseudorapidity correlations observed in high-multiplicity p–Pb col ...Daha fazlası

Anisotropic Flow of Charged Particles in Pb-Pb Collisions at 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We report the first results of elliptic (v2), triangular (v3), and quadrangular (v4) flow of charged particles in Pb-Pb collisions at a center-of-mass energy per nucleon pair of sNN 1⁄4 5.02 TeV with the ALICE detector at the CERN Large Hadron Collider. The measurements are performed in the central pseudorapidity region jηj < 0.8 and for the transverse momentum range 0.2 < pT < 5 GeV=c. The anisotropic flow is measured using two-particle correlations with a pseudorapidity gap greater than one unit and with the multiparticle cumulant method. Compared to results from Pb-Pb collisions at sNN = 2. ...Daha fazlası

Measurement of anti-3 He nuclei absorption in matter and impact on their propagation in the Galaxy

KARASU UYSAL, Ayben | ALICE Collaboration

In our Galaxy, light antinuclei composed of antiprotons and antineutrons can be produced through high-energy cosmic-ray collisions with the interstellar medium or could also originate from the annihilation of dark-matter particles that have not yet been discovered. On Earth, the only way to produce and study antinuclei with high precision is to create them at high-energy particle accelerators. Although the properties of elementary antiparticles have been studied in detail, the knowledge of the interaction of light antinuclei with matter is limited. We determine the disappearance probability of ...Daha fazlası

Azimuthal Anisotropy of Heavy-Flavor Decay Electrons in p-Pb Collisions at sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Angular correlations between heavy-flavor decay electrons and charged particles at midrapidity pffiffiffiffiffiffiffi (jηj < 0.8) are measured in p-Pb collisions at sNN 1⁄4 5.02 TeV. The analysis is carried out for the 0%–20% (high) and 60%–100% (low) multiplicity ranges. The jet contribution in the correlation distribution from high-multiplicity events is removed by subtracting the distribution from low-multiplicity events. An azimuthal modulation remains after removing the jet contribution, similar to previous observations in two-particle angular correlation measurements for light-flavor had ...Daha fazlası

Pseudorapidity dependence of the anisotropic flow of charged particles in Pb–Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We present measurements of the elliptic (v2 ), triangular (v3 ) and quadrangular (v4 ) anisotropic azimuthal flow over a wide range of pseudorapidities (−3.5 < η < 5). The measurements are performed with Pb– Pb collisions at √sNN = 2.76 TeV using the ALICE detector at the Large Hadron Collider (LHC). The flow harmonics are obtained using two- and four-particle correlations from nine different centrality intervals covering central to peripheral collisions. We find that the shape of vn(η) is largely independent of centrality for the flow harmonics n = 2–4, however the higher harmonics fall off m ...Daha fazlası

Anisotropic flow in Xe–Xe collisions at √sNN = 5.44 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The first measurements of anisotropic flow coefficients vn for mid-rapidity charged particles in Xe– Xe collisions at √sNN = 5.44 TeV are presented. Comparing these measurements to those from Pb–Pb collisions at √sNN = 5.02 TeV, v2 is found to be suppressed for mid-central collisions at the same centrality, and enhanced for central collisions. The values of v3 are generally larger in Xe–Xe than in Pb–Pb at a given centrality. These observations are consistent with expectations from hydrodynamic predictions. When both v2 and v3 are divided by their corresponding eccentricities for a variety of ...Daha fazlası
