Quarkonium production in p-Pb collisions with ALICE

KARASU UYSAL, Ayben | ALICE Collaboration

ALICE has measured quarkonium production in p-Pb collisions at backward (-4.46 < y(cms) < 2.96), mid (-1.37 < y(cms) < 0.43) and forward (2.03 < y(cms) < 3,53) rapidity (y) regions down to zero transverse momentum (p(T)). The inclusive J/psi production has been studied at mid-y in p-Pb interactions at root S-NN = 5.02 TeV and at forward and backward y in p-Pb collisions at root S-NN = 5.02 TeV and 8.16 TeV. The comparison of the J/psi production to the one of the loosely bound psi(2S) state is discussed, together with new results on the nuclear modification factors of the gamma(1S) and gamma(2 ...Daha fazlası

Elliptic flow of identified hadrons in small collisional systems measured with ALICE

KARASU UYSAL, Ayben | ALICE Collaboration

Recent observations of long-range multi-particle azimuthal correlations in p-Pb and high multiplicity pp collisions provided new insights into collision dynamics and opened a possibility to study collective effects in these small systems. New measurements of p(T)-differential elliptic flow (v(2)) coefficient for inclusive charged hadrons as well as a variety of identified particle species in p-Pb collisions at root s(NN) = 5.02 TeV are presented. The data was collected by ALICE during the LHC Run 2 data taking. Besides high precision measurements of v(2)(P-T) for pi(+/-), K-+/- and p((p) over ...Daha fazlası

Multiplicity dependence of strangeness and hadronic resonance production in pp and p-Pb collisions with ALICE at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

One of the key results of the LHC Run 1 was the observation of an enhanced production of strange particles in high multiplicity pp and p-Pb collisions at,root s(NN) 7 and 5.02 TeV, respectively. The strangeness enhancement is investigated by measuring the evolution with multiplicity of single-strange and multi-strange baryon production relative to non-strange particles. A smooth increase of strange particle yields relative to the non-strange ones with event multiplicity has been observed in such systems. We report the latest results on multiplicity dependence of strange and multi-strange hadro ...Daha fazlası

ALICE measurements of flow coefficients and their correlations in small (pp and p-Pb) and large (Xe-Xe and Pb-Pb) collision systems

KARASU UYSAL, Ayben | ALICE Collaboration

Many observables which are used as a signature of the collective effects in heavy-ion collisions when measured in high multiplicity pp and pA interactions reveal a very similar behaviour. We will present first measurements of different order flow coefficients and their magnitude correlations for data collected by ALICE during the LHC Run 2 operation, which includes pp collisions at root s = 13 TeV, p-Pb at root s(NN)= 5.02 TeV, Xe-Xe at root sNN = 5.44 TeV and Pb-Pb collisions at root s(NN) = 5.02 TeV. Such a broad spectrum of colliding systems with different energies and wide range of multipl ...Daha fazlası

Addressing the hypertriton lifetime puzzle with ALICE at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

The ALICE Collaboration collected a large data sample of Pb-Pb collisions at root S-NN = 5.02 TeV in 2015 at the Large Hadron Collider (LHC) and the excellent particle identification (PID) capabilities allow for the detection of rarely produced (anti-)hypernuclei. In particular, the (anti-)hypertriton, H-3(Lambda), which is a bound state of a proton, a neutron and a A, is the lightest known hypernucleus. The results on the H-3(Lambda) production are compared with the predictions from a model based on coalescence approach and from statistical-thermal models to investigate the production mechani ...Daha fazlası

Balance functions of (un)identified hadrons in Pb-Pb, p-Pb, and pp collisions at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

In ultrarelativistic heavy-ion collisions, correlations of particles with opposite quantum numbers provide insight into quark production mechanisms and time scales, collective motion, and re-scattering in the hadronic phase. The longitudinal and azimuthal widths of balance functions for charged kaons and charged pions are used to examine the two-wave quark production model proposed to explain quark-antiquark production within the QGP, which predicts a large increase in up and down quark pairs relative to strange quark pairs around the time of hadronization. Balance functions are also analyzed ...Daha fazlası

Investigating correlated fluctuations of conserved charges with net-Λ fluctuations in Pb–Pb collisions at ALICE

KARASU UYSAL, Ayben | ALICE Collaboration

Event-by-event fluctuations of conserved charges such as electric charge, strangeness, and baryon number - in ultrarelativistic heavy-ion collisions provide insight into the properties of the quark-gluon plasma and the QCD phase diagram. They can be related to the higher moments of the multiplicity distributions of identified particles, such as the A baryon which carries both strangeness and baryon number and is thus of particular interest. We present the first measurement of net-A fluctuations in Pb-Pb collisions at root s(NN)=5.02 TeV as a function of centrality and the pseudorapidity accept ...Daha fazlası

Hadronic resonances, strange and multi-strange particle production in Xe-Xe and Pb-Pb collisions with ALICE at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

We present measurements of hadronic resonance, strange and multi-strange particle production in collisions of Xe-Xe and Pb-Pb at the center-of-mass energies of root s(NN) = 5.44 and 5.02 TeV, respectively, by the ALICE collaboration at the LHC. Particle ratios are presented as a function of multiplicity for K-s(0), Lambda, Xi(-), (Xi) over bar (+), Omega(-), (Omega) over bar (+), rho(770)(0), K{*}(892)(0), phi(1020) and Lambda(1520). Our results are discussed and compared with predictions of QCD-inspired event generators. Additionally, comparisons with lower energy measurements and smaller sys ...Daha fazlası

Higher moment fluctuations of identified particle distributions from ALICE

KARASU UYSAL, Ayben | ALICE Collaboration

Cumulants of conserved charges fluctuations are regarded as a potential tool to study the criticality in the QCD phase diagram and to determine the freeze-out parameters in a model-independent way. At LHC energies, the measurements of the ratio of the net-baryon (net-proton) cumulants can be used to test the lattice QCD predictions. In this work, we present the first measurements of cumulants of the net-proton number distributions up to 4th order in Pb-Pb collisions at root s(NN) = 2.76 and 5.02 TeV as a function of collision centrality. We compare our cumulant ratios results with the STAR exp ...Daha fazlası

Relationship of modernism, postmodernism and reflections of it on education

KAHRAMAN, Ayşe Derya

Making Modernism and Postmodernism a different sense of social life caused creation of different life and thinking styles. Modernism as a result of enlightening after the 18th century has taken its place in every area of the society. Post modern word has been defined as the further level of modernism. Every two kind of thinking styles have been effective at every point of life, also it affected education. Main elements of modern culture and postmodern education are combined and are being integrated with educational programs. The relationship of modernism and postmodernism is being examined sin ...Daha fazlası

Constraining production models with light (anti-)nuclei measurements in small systems with ALICE at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

The production of deuterons and anti-deuterons in pp collisions at root s = 7 and 13 TeV has been studied as a function of charged-particle multiplicity using the ALICE detector at the LHC. The preliminary results are shown here, together with those obtained in heavy-ion collisions. They are presented by focusing the discussion on the comparison with expectations from hadron-coalescence models.
