Combined search for anomalous pseudoscalar HVV couplings in VH(H→bb‾) production and H → VV decay

Vardan Khachatryan, +2344 more
- 10 Aug 2016 - 
TL;DR: In this paper, anomalous pseudoscalar couplings of the Higgs boson H to electroweak vector bosons V (=W or Z) in a sample of proton-proton collision events corresponding to an integrated luminosity of 18.9 fb^(−1) at a center-of-mass energy of 8 TeV are presented.
Journal ArticleDOI

Search for heavy neutrinos or third-generation leptoquarks in final states with two hadronically decaying τ leptons and two jets in proton-proton collisions at √s = 13 TeV

Vardan Khachatryan, +2342 more
- 14 Mar 2017 - 
TL;DR: In this article, a search for new particles has been conducted using events with two high transverse momentum (pt) tau leptons that decay hadronically, at least two high-pt jets, and missing transverse energy from the tau bb decays.
Journal ArticleDOI

Ghrelin-induced food intake and adiposity depend on central mTORC1/S6K1 signaling.

Darko Stevanovic, +13 more
- 05 Dec 2013 - 
TL;DR: It is proposed that ghrelin-induced hyperphagia, adiposity and insulin secretion are controlled by a central nervous system involving the mTORC1/S6K1 pathway.
Journal ArticleDOI

Search for top squark and higgsino production using diphoton higgs boson decays

S. Chatrchyan, +2193 more
- 25 Apr 2014 - 
TL;DR: Results are presented of a search for a "natural" supersymmetry scenario with gauge mediated symmetry breaking and lower limits at the 95% confidence level are set, excluding the top squark mass below 360 to 410 GeV, depending on the Higgsino mass.
Journal ArticleDOI

Performance of the CMS hadron calorimeter with cosmic ray muons and LHC beam data

S. Chatrchyan, +2464 more
- 01 Dec 2010 - 
TL;DR: The CMS Hadron Calorimeter in the barrel, endcap and forward regions is fully commissioned as mentioned in this paper, and the energy response of the HCAL determined from test beam data has been checked.
