Measurement of quarkonium production cross sections in pp collisions at s=13TeV

Albert M. Sirunyan, +2247 more
- 10 May 2018 - 
TL;DR: Differential production cross sections of prompt J/ψ and ψ(2S) charmonium and ϒ(nS) (n=1,2,3) bottomonium states are measured in proton-proton collisions at √s = 13 TeV, with data collected by the CMS detector at the LHC, corresponding to an integrated luminosity of 2.3 fb^(−1) for the J/ ψ and 2.7 fb+1 for the other mesons as mentioned in this paper.
Journal ArticleDOI

Measurement of prompt ψ (2S) to J /ψ yield ratios in Pb-Pb and p - p collisions at sNN =2.76 TeV

Vardan Khachatryan, +2229 more
- 31 Dec 2014 - 
TL;DR: In this article, the double ratio of measured yields (N phi((2S))/NJ/(Pb-Pb)/N-psi(2S)/NJ/psi)(p-p) is computed in three collision centrality bins and two kinematic ranges.
Journal ArticleDOI

Precise Mapping of the Magnetic Field in the CMS Barrel Yoke using Cosmic Rays

S. Chatrchyan, +2464 more
- 01 Dec 2010 - 
TL;DR: In this paper, a detailed map of the magnetic field is required for the accurate simulation and reconstruction of physics events in the CMS detector, not only in the inner tracking region inside the solenoid but also in the large and complex structure of the steel yoke, which is instrumented with muon chambers.
Journal ArticleDOI

Search for heavy Majorana neutrinos in μ±μ±+jets and e±e±+ jets events in pp collisions at s=7 TeV

S. Chatrchyan, +2210 more
- 22 Oct 2012 - 
TL;DR: In this paper, a search is performed for heavy Majorana neutrinos (N) using an event signature defined by two like-sign charged leptons of the same flavour and two jets.
Journal ArticleDOI

Arabinoxylan-enriched meal increases serum ghrelin levels in healthy humans.

Matthias Möhlig, +9 more
- 01 May 2005 - 
TL;DR: In subjects with normal glucose regulation, the AX-enriched breakfast increased ghrelin levels without any significant difference in glucose or insulin response, so this effect is unlikely to be mediated by insulin, but the underlying mechanism remains to be elucidated.
