Search for the pair production of third-generation squarks with two-body decays to a bottom or charm quark and a neutralino in proton-proton collisions at root s=13 TeV

Albert M. Sirunyan, +2240 more
- 10 Mar 2018 - 
TL;DR: In this paper, a search for the pair production of third-generation squarks in proton-proton collision events with two-body decays to bottom or charm quarks and a neutralino, which produces a significant imbalance in the transverse momentum.
Journal ArticleDOI

Measurement of top quark–antiquark pair production in association with a W or Z boson in pp collisions at √s = 8 TeV

Khachatryan, +2130 more
- 17 Sep 2014 - 
TL;DR: In this article, a measurement of the cross section for the production of top quark-antiquark pairs (ttbar) in association with a vector boson V (W or Z) in proton-proton collisions at square root(s) = 8 TeV is presented.
Journal ArticleDOI

Recent attoclock measurements of strong field ionization

Andreas Pfeiffer, +3 more
TL;DR: In this paper, the authors demonstrated the attoclock with the goal to measure the tunneling delay time in laser-induced ionization of helium and argon atoms, with surprising results.

Measurement of the W+W− cross section in pp collisions at $\sqrt{s} = 7\mbox{ TeV}$ and limits on anomalous WWγ and WWZ couplings

S. Chatrchyan, +2188 more
TL;DR: In this article, a measurement of W+W− production in pp collisions at $\sqrt{s} = 7~\mathrm{TeV}$ was presented, and the data were collected with the CMS detector at the LHC, and correspond to an integrated luminosity of 4.92±0.11−1.2 (lum.)
Journal ArticleDOI

Relative modification of prompt ψ (2S) and J /ψ yields from pp to PbPb collisions at sNN =5.02 TeV

Albert M. Sirunyan, +2282 more
- 20 Apr 2017 - 
TL;DR: The relative modification of the prompt ψ(2S) and J/ψ yields from pp to PbPb collisions, at the center-of-mass energy of 5.02 TeV per nucleon pair, is presented.
