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

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

J/ψ suppression at forward rapidity in Pb–Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The inclusive J/ψ production has been studied in Pb–Pb and pp collisions at the centre-of-mass energy per nucleon pair √sNN = 5.02 TeV, using the ALICE detector at the CERN LHC. The J/ψ meson is reconstructed, in the centre-of-mass rapidity interval 2.5 < y < 4 and in the transverse-momentum range pT < 12 GeV/c, via its decay to a muon pair. In this Letter, we present results on the inclusive J/ψ cross section in pp collisions at √s = 5.02 TeV and on the nuclear modification factor RAA. The latter is presented as a function of the centrality of the collision and, for central collisions, as a f ...Daha fazlası

Measurement of charged jet suppression in Pb-Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

A measurement of the transverse momentum spectra of jets in Pb–Pb col- lisions at √sNN = 2.76TeV is reported. Jets are reconstructed from charged particles using the anti-kT jet algorithm with jet resolution parameters R of 0.2 and 0.3 in pseudo- rapidity |η| < 0.5. The transverse momentum pT of charged particles is measured down to 0.15 GeV/c which gives access to the low pT fragments of the jet. Jets found in heavy-ion collisions are corrected event-by-event for average background density and on an inclusive basis (via unfolding) for residual background fluctuations and detector effects.

First measurement of jet mass in Pb–Pb and p–Pb collisions at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

This letter presents the first measurement of jet mass in Pb–Pb and p–Pb collisions at √sNN = 2.76 TeV and √sNN = 5.02 TeV, respectively. Both the jet energy and the jet mass are expected to be sensitive to jet quenching in the hot Quantum Chromodynamics (QCD) matter created in nuclear collisions at collider energies. Jets are reconstructed from charged particles using the anti-kT jet algorithm and resolution parameter R = 0.4. The jets are measured in the pseudorapidity range |ηjet | < 0.5 and in three intervals of transverse momentum between 60 GeV/c and 120 GeV/c. The measurement of the jet ...Daha fazlası

Measurement of the inclusive J/ψ polarization at forward rapidity in pp collisions at √s = 8 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We report on the measurement of the inclusive J/ψ polarization parameters in pp collisions at a center of mass energy √s = 8 TeV with the ALICE detector at the LHC. The analysis is based on a data sample corresponding to an integrated luminosity of 1.23 pb−1. J/ψ resonances are reconstructed in their di-muon decay channel in the rapidity interval 2.5 < y < 4.0 and over the transverse-momentum interval 2 < pT < 15 GeV/c. The three polarization param- eters (λθ , λφ , λθ φ ) are measured as a function of pT both in the helicity and Collins-Soper reference frames. The mea- sured J/ψ polarization ...Daha fazlası

Inclusive J/ψ production in Xe–Xe collisions at √sNN = 5.44 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Inclusive J/ψ production is studied in Xe–Xe interactions at a centre-of-mass energy per nucleon pair of √sNN = 5.44 TeV, using the ALICE detector at the CERN LHC. The J/ψ meson is reconstructed via its decay into a muon pair, in the centre-of-mass rapidity interval 2.5 < y < 4 and down to zero transverse momentum. In this Letter, the nuclear modification factors RAA for inclusive J/ψ, measured in the centrality range 0–90% as well as in the centrality intervals 0–20% and 20–90% are presented. The RAA values are compared to previously published results for Pb–Pb collisions at √sNN = 5.02 TeV a ...Daha fazlası

الشمولية الدلالية والمنهجية بين قصتين مختلفتين: مثال قصتي يوسف وموسى

SÖNMEZ, Ramazan

Makalenin konusu Yusuf ve Musa kıssalarındaki anlam bütünlüğüdür. Kur’an kıssaları çok olmakla beraber bu iki kıssanın ortak noktası Kur’an’ın mesajı hususunda kendi içlerinde bir tamlık ve bütünlük taşımalarıdır. Bu nedenle çalışmanın örneklemini bu iki kıssa oluşturmuştur. Çalışmada Yusuf ve Musa kıssalarının hem yöntemsel hem de anlamsal bütünlüğe sahip olduklarını, dolayısıyla Kur’an’ın tek kaynaktan, tek çıkış noktasından ürediğini göstermek temel hedeftir. Farklı iki kıssa, farklı sureler anlamına gelirken değişkenlerin ve farklılıkların çok fazla olduğu iki metinde Kur’an’ın ana mesajla ...Daha fazlası

Study of cosmic ray events with high muon multiplicity using the ALICE detector at the CERN Large Hadron Collider

KARASU UYSAL, Ayben | ALICE Collaboration

ALICE is one of four large experiments at the CERN Large Hadron Collider near Geneva, specially designed to study particle production in ultra-relativistic heavy-ion colli- sions. Located 52 meters underground with 28 meters of overburden rock, it has also been used to detect muons produced by cosmic ray interactions in the upper atmosphere. In this paper, we present the multiplicity distribution of these atmospheric muons and its compari- son with Monte Carlo simulations. This analysis exploits the large size and excellent tracking capability of the ALICE Time Projection Chamber. A special em ...Daha fazlası

There is a continuous search for the safest abdominal entry technique, considering the recent progressions in laparoscopic surgery. In this study, we wanted to share a novel technique that we have identified for safe laparoscopic entry in obese patients. A total of 2936 laparoscopic operations were performed in general surgery, urology, and gynecology departments of Mevlana University from 2003 to 2013. The number of patients with a body mass index (BMI) ≥30 was 764. We have identified a new technique for a safer first entry in these patients. Direct open surgery, insertion techniques in which ...Daha fazlası
