Search for neutral color-octet weak-triplet scalar particles in proton-proton collisions at √s= 8TeV

Vardan Khachatryan, +2363 more
- 29 Sep 2015 - 
TL;DR: In this paper, a search for pair production of neutral color octet weak-triplet scalar particles (Theta) was performed in processes where one Theta decays to a pair of b quark jets and the other to a Z boson plus a jet, with the z boson decaying to either electrons or muons.
