p-p, p-lambda, and lambda-lambda correlations studied via femtoscopy in pp reactions at √s = 7 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We report on the first femtoscopic measurement of baryon pairs, such as p-p, p-, and , measured by ALICE at the Large Hadron Collider (LHC) in proton-proton collisions at √s = 7 TeV. This study demonstrates the feasibility of such measurements in pp collisions at ultrarelativistic energies. The femtoscopy method is employed to constrain the hyperon-nucleon and hyperon-hyperon interactions, which are still rather poorly understood. A new method to evaluate the influence of residual correlations induced by the decays of resonances and experimental impurities is hereby presented. The p-p, p-, and ...Daha fazlası

Charged jet cross section and fragmentation in proton-proton collisions pffiffi at s=7TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Azimuthally-differential femtoscopic measurements, being sensitive to spatio-temporal characteristics of the source as well as to the collective velocity fields at freeze out, provide very important information on the nature and dynamics of the system evolution. While the HBT radii oscillations relative to the second harmonic event plane measured recently reflect mostly the spatial geometry of the source, model studies have shown that the HBT radii oscillations relative to the third harmonic event plane are predominantly defined by the velocity fields. In this Letter, we present the first resu ...Daha fazlası

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

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

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

Dielectron measurements in pp and Pb-Pb colllisions with ALICE at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

The production of low-mass dielectrons is one of the most promising tools for the investigation of chiral symmetry restoration and thermal radiation from the QGP created in heavy-ion collisions. To single out the signal characteristics of the QGP, it is crucial to understand the primordial e+e− pair production in vacuum, i.e. in inelastic proton-proton (pp) collisions. Low-mass dielectrons have been measured with ALICE at the LHC in pp collisions at √s = 7 and 13 TeV, and in Pb–Pb collisions at √sNN = 2.76 TeV. An overview of the results on dielectron production is presented, together with the ...Daha fazlası

Measurement of jet radial profiles in Pb–Pb collisions at sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The jet radial structure and particle transverse momentum (pT) composition within jets are presented in centrality-selected Pb–Pb collisions at √sNN = 2.76 TeV. Track-based jets, which are also called charged jets, were reconstructed with a resolution parameter of R = 0.3 at midrapidity |ηch jet| < 0.6 for transverse momenta pT, ch jet = 30–120 GeV/c. Jet–hadron correlations in relative azimuth and pseudorapidity space (φ,η) are measured to study the distribution of the associated particles around the jet axis for different pT,assoc-ranges between 1 and 20 GeV/c. The data in Pb–Pb collisions a ...Daha fazlası

Study of the Λ–Λ interaction with femtoscopy correlations in and p–Pb collisions at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

This work presents new constraints on the existence and the binding energy of a possible Λ-Λ bound state, the H-dibaryon, derived from Λ-Λ femtoscopic measurements by the ALICE collaboration. The results are obtained from a new measurement using the femtoscopy technique in pp collisions at s√=13 TeV and p-Pb collisions at sNN‾‾‾‾√=5.02 TeV, combined with previously published results from p-Pb collisions at s√=7 TeV. The Λ-Λ scattering parameter space, spanned by the inverse scattering length f−10 and the effective range d0, is constrained by comparing the measured Λ-Λ correlation function with ...Daha fazlası

Measurement of charged jet cross section in pp collisions at 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The cross section of jets reconstructed from charged particles is measured in the transverse momentum range of 5 < pT < 100 GeV=c in pp collisions at the center-of-mass energy of s 1⁄4 5.02 TeV with theALICE detector. The jets are reconstructed using the anti-kT algorithm with resolution parameters R 1⁄4 0.2, 0.3, 0.4, and 0.6 in the pseudorapidity range jηj < 0.9 − R. The charged jet cross sections are compared with the leading-order (LO) and to next-to-leading-order (NLO) perturbative quantum chromodynamics (pQCD) calculations. It is found that the NLO calculations agree better with the meas ...Daha fazlası

Measurement of the inclusive isolated photon production cross section in pp collisions at √s = 7 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The production cross section of inclusive iso- lated photons has been measured by the ALICE experiment at the CERN LHC in pp collisions at a centre-of-momentum energy of √s = 7 TeV. The measurement is performed with the electromagnetic calorimeter EMCal and the central track- ing detectors, covering a range of |η| < 0.27 in pseudora- pidity and a transverse momentum range of 10 < pTγ < 60 GeV/c. The result extends the pT coverage of previously published results of the ATLAS and CMS experiments at the same collision energy to smaller pT. The measurement is compared to next-to-leading order pert ...Daha fazlası
