Search for Quark Compositeness with the Dijet Centrality Ratio in pp Collisions at root s=7 TeV

Vardan Khachatryan, +2200 more
- 20 Dec 2010 - 
TL;DR: In this article, a search for quark compositeness in the form of quark contact interactions, based on hadronic jet pairs (dijets) produced in proton-proton collisions at sqrt(s) = 7 TeV, is described.
Journal ArticleDOI

Albert M. Sirunyan, +2356 more
- 05 Jul 2018 - 
TL;DR: In this paper, a search for the electroweak production of supersymmetric particles in protonproton collisions at a center-of-mass energy of 13TeV is presented in final states with a tau lepton pair.
Journal ArticleDOI

Search for Evidence of the Type-III Seesaw Mechanism in Multilepton Final States in Proton-Proton Collisions at s =13 TeV

Albert M. Sirunyan, +2234 more
- 01 Dec 2017 - 
TL;DR: The results are used to place limits on the production of heavy fermions of the type-III seesaw model as a function of the branching ratio to each lepton flavor.
Journal ArticleDOI

Search for anomalous single top quark production in association with a photon in pp collisions at √s = 8 TeV

Vardan Khachatryan, +2356 more
- 06 Apr 2016 - 
TL;DR: In this paper, a search for flavor changing neutral currents (FCNC) through single top quark production in association with a photon is presented, and upper limits at the 95% confidence level are set on the tuγ and tcγ anomalous couplings.
Journal ArticleDOI
