Charged jet cross sections and properties in proton-proton collisions at root s=7 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The differential charged jet cross sections, jet fragmentation distributions, and jet shapes are measured in pffiffi minimum bias proton-proton collisions at center-of-mass energy s 1⁄4 7 TeV using the ALICE detector at the LHC. Jets are reconstructed from charged particle momenta in the midrapidity region using the sequential recombination kT and anti-kT as well as the SISCone jet finding algorithms with several resolution parameters in the range R 1⁄4 0.2–0.6. Differential jet production cross sections measured with the three jet finders are in agreement in the transverse momentum (p ) inter ...Daha fazlası

K∗(892)0 and φ(1020) production in Pb-Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The yields of the K∗(892)0 and φ(1020) resonances are measured in Pb-Pb collisions at √sNN = 2.76 TeV through their hadronic decays using the ALICE detector. The measurements are performed in multiple centrality intervals at mid-rapidity (|y| < 0.5) in the transverse-momentum ranges 0.3 < pT < 5 GeV/c for the K∗(892)0 and 0.5 < pT < 5 GeV/c for the φ(1020). The yields of K∗(892)0 are suppressed in central Pb-Pb collisions with respect to pp and peripheral Pb-Pb collisions (perhaps due to rescattering of its decay products in the hadronic medium), while the longer-lived φ(1020) meson is not sup ...Daha fazlası

KAYIP KAÇAK BEDELİNİN HUKUKİ BAKIMDAN DEĞERLENDİRİLMESİ

YAVUZ, Mustafa

Electricity sector is reorganized by the Electricity Market Law. This transformation enabled liberalization, dissociation of operations, setting of each operation according to their real cost while ensuring the transparence in the electricity market. Especially within the scope of “principle of transparency” denoted by the first clause of the law, the composition of electricity costs from producer to consumers and weight of each component activity on the bill have become visible. Thus, the theft and losses rates of electricity -which have been existing for years, but their weights on the bill ...Daha fazlası

Precision measurement of the mass difference between light nuclei and anti-nuclei

KARASU UYSAL, Ayben | ALICE Collaboration

The measurement of the mass differences for systems bound by the strong force has reached a very high precision with protons and anti-protons1,2. The extension of such measure- ment from (anti-)baryons to (anti-)nuclei allows one to probe any difference in the interactions between nucleons and anti- nucleons encoded in the (anti-)nuclei masses. This force is a remnant of the underlying strong interaction among quarks and gluons and can be described by effective theories3, but cannot yet be directly derived from quantum chromodynamics. Here we report a measurement of the difference between the ...Daha fazlası

Inclusive photon production at forward rapidities in proton–proton collisions at √s = 0.9, 2.76 and 7 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The multiplicity and pseudorapidity distribu- tions of inclusive photons have been measured at forward rapidities (2.3 < η < 3.9) in proton–proton collisions at three center-of-mass energies, √s = 0.9, 2.76 and 7 TeV using the ALICE detector. It is observed that the increase in the average photon multiplicity as a function of beam energy is compatible with both a logarithmic and a power-law dependence. The relative increase in average photon multi- plicity produced in inelastic pp collisions at 2.76 and 7 TeV center-of-mass energies with respect to 0.9 TeV are 37.2 ± 0.3% (stat) ± 8.8% (sys) a ...Daha fazlası

Measurement of jet suppression in central Pb–Pb collisions at 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The transverse momentum (pT) spectrum and nuclear modification factor (RAA) of reconstructed jets in 0–10% and 10–30% central Pb–Pb collisions at √sNN = 2.76 TeV were measured. Jets were reconstructed using the anti-kT jet algorithm with a resolution parameter of R = 0.2 from charged and neutral particles, utilizing the ALICE tracking detectors and Electromagnetic Calorimeter (EMCal). The jet pT spectra are reported in the pseudorapidity interval of |ηjet| < 0.5 for 40 < pT, jet < 120 GeV/c in 0–10% and for 30 < pT, jet < 100 GeV/c in 10–30% collisions. Reconstructed jets were required to cont ...Daha fazlası

Forward-backward multiplicity correlations in pp collisions at √s = 0.9, 2.76 and 7 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The strength of forward-backward (FB) multiplicity correlations is measured √ s = 0.9, 2.76 and 7TeV. The measurement is performed in the central pseudorapidity region (|η| < 0.8) for the transverse momentum pT > 0.3GeV/c. Two separate pseudorapidity windows of width (δη) ranging from 0.2 to 0.8 are chosen symmetrically around η = 0. The multiplicity correlation strength (bcorr) is studied as a function of the pseudorapidity gap (ηgap) between the two windows as well as the width of these windows. The correlation strength is found to decrease with increasing ηgap and shows a non-linear increas ...Daha fazlası

Rule-based mamdani-type fuzzy modeling of performance proton exchange membrane fuel cell with carbon nano tube

ATA, Sadık | DİNÇER, Kevser

In this study, performance of proton exchange membrane (PEM) fuel cell was experimentally investigated and modeled with Rule-Based Mamdani-Type Fuzzy (RBMTF) modeling technique. Coating on the anode side of the membrane of PEM fuel cell was accomplished with the spin method by using carbon nanotube (CNT). In the experimental study, current and voltage performances before and after coating have been recorded at 20oC and then are compared to each other. It was determined the increasing of the performance of PEM fuel cell when coated with CNT. Input-output parameters were described by RBMTF if-th ...Daha fazlası

Centrality dependence of inclusive J/ψ production in p-Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We present a measurement of inclusive J/ψ production in p-Pb collisions at √sNN = 5.02TeV as a function of the centrality of the collision, as estimated from the energy deposited in the Zero Degree Calorimeters. The measurement is performed with the ALICE detector down to zero transverse momentum, pT, in the backward (−4.46 < ycms < −2.96) and forward (2.03 < ycms < 3.53) rapidity intervals in the dimuon decay channel and in the mid-rapidity region (−1.37 < ycms < 0.43) in the dielectron decay channel. The backward and forward rapidity intervals correspond to the Pb-going and p-going direction ...Daha fazlası

The analysis was performed using minimum bias events and events triggered by the electromagnetic calorimeter. Predictions from perturbative QCD calculations agree with the data within the theoretical and experimental uncertainties.

The measurement of primary π ± , K ± , p and p production at mid-rapidity (|y| < 0.5) in proton–proton col- lisions at √s = 7 TeV performed with a large ion collider experiment at the large hadron collider (LHC) is reported. Particle identification is performed using the specific ioni- sation energy-loss and time-of-flight information, the ring- imaging Cherenkov technique and the kink-topology identifi- cation of weak decays of charged kaons. Transverse momen- tum spectra are measured from 0.1 up to 3 GeV/c for pions, from 0.2 up to 6 GeV/c for kaons and from 0.3 up to 6 GeV/c for protons. Th ...Daha fazlası
