We present the first measurement at the LHC of exclusive J=ψ photoproduction off protons, in pffiffiffiffiffiffiffi ultraperipheral proton-lead collisions at sNN 1⁄4 5.02 TeV. Events are selected with a dimuon pair produced either in the rapidity interval, in the laboratory frame, 2.5 < y < 4 (p-Pb) or −3.6 < y < −2.6 (Pb-p), and no other particles observed in the ALICE acceptance. The measured cross sections σðγ þ p → J=ψ þ pÞ are 33.2 2.2ðstatÞ 3.2ðsystÞ 0.7ðtheorÞ nb in p-Pb and 284 36ðstatÞþ27ðsystÞ −32 26ðtheorÞ nb in Pb-p collisions. We measure this process up to about 700 GeV in the γp ...Daha fazlası
A measurement of the production of prompt Λ+c baryons in Pb-Pb collisions at sNN−−−√=5.02 TeV with the ALICE detector at the LHC is reported. The Λ+c and Λ¯¯¯¯−c were reconstructed at midrapidity (|y|< 0.5) via the hadronic decay channel Λ+c→pK0S (and charge conjugate) in the transverse momentum and centrality intervals 6< pT< 12 GeV/c and 0-80%. The Λ+c/D0 ratio, which is sensitive to the charm quark hadronisation mechanisms in the medium, is measured and found to be larger than the ratio measured in minimum-bias pp collisions at s√=7 TeV and in p-Pb collisions at sNN−−−√=5.02 TeV.

The production of electrons from heavy-flavour hadron decays was measured as a function of transverse momentum (pT) in minimum-bias p–Pb collisions at √sNN = 5.02 TeV using the ALICE detector at the LHC. The measurement covers the pT interval 0.5 < pT < 12 GeV/c and the rapidity range −1.065 < ycms < 0.135 in the centre-of-mass reference frame. The contribution of electrons from background sources was subtracted using an invariant mass approach. The nuclear modification factor RpPb was calculated by comparing the pT-differential invariant cross section in p–Pb collisions to a pp reference at √ ...Daha fazlası
The ALICE Collaboration has studied the inclusive production of the char- monium state ψ(2S) in proton-lead (p-Pb) collisions at the nucleon-nucleon centre of mass energy √sNN = 5.02 TeV at the CERN LHC. The measurement was performed at forward (2.03 < ycms < 3.53) and backward (−4.46 < ycms < −2.96) centre of mass rapidities, studying the decays into muon pairs. In this paper, we present the inclusive production cross sections σψ(2S), both integrated and as a function of the transverse momentum pT, for the two ycms domains. The results are compared to those obtained for the 1S vector state (J ...Daha fazlası
We present a study of the inclusive charged- particle transverse momentum ( pT ) spectra as a function of charged-particle multiplicity density at mid-pseudorapidity, d Nch /dη, in pp collisions at √s = 5.02 and 13 TeV covering the kinematic range |η| < 0.8 and 0.15 < pT < 20 GeV/c. The results are presented for events with at least one charged particle in |η| < 1 (INEL > 0). The pT spectra are reported for two multiplicity estimators covering different pseudo- rapidity regions. The pT spectra normalized to that for INEL> 0 show little energy dependence. Moreover, the high-pT yields of charged ...Daha fazlası
ÖZET Kalp yetmezliği ve Akut Lenfoblastik Lösemi (ALL) tanısı alan hastaların kompleks ilaç tedavileri, uzun süre hastanede yatmaları ve enfeksiyon risklerinin yüksek olması nedeniyle stres düzeyleri fazladır. Ayrıca hastaların çoğunun ALL ve kalp yetmezliği hakkında bilgi düzeyinin yetersiz olduğu, diyet ve tedavi uyumu gibi öz bakım davranışlarını yerine getiremediği, tekrarlı yatışları azaltma, tedaviye bağlı komplikasyonları önleme gibi istenen hedeflere ulaşılamadığı görülmektedir. Hemşirelik alanında ve uygulamalarında sık kullanılan modellerden biri olan Neuman Sistemler Modeli (NSM), G ...Daha fazlası
Two-particle angular correlations between trigger particles in the forward pseudorapidity range (2.5 < |η| < 4.0) and associated particles in the central range (|η| < 1.0) are measured with the ALICE detector in p–Pb collisions at a nucleon–nucleon centre-of-mass energy of 5.02 TeV. The trigger particles are reconstructed using the muon spectrometer, and the associated particles by the central barrel tracking detectors. In high-multiplicity events, the double-ridge structure, previously discovered in two-particle angular correlations at midrapidity, is found to persist to the pseudorapidity ra ...Daha fazlası
