Combined measurements of Higgs boson couplings in proton–proton collisions at √s=13Te

Albert M. Sirunyan, +2268 more
TL;DR: Combined measurements of the production and decay rates of the Higgs boson, as well as its couplings to vector bosons and fermions, are presented and constraints are placed on various two Higgs doublet models.
Journal ArticleDOI

Search for dark matter, extra dimensions, and unparticles in monojet events in proton–proton collisions at √s = 8 TeV

Vardan Khachatryan, +2122 more
TL;DR: In this paper, a search for particle dark matter (DM), extra dimensions, and unparticles using events containing a jet and an imbalance in transverse momentum was conducted at the LHC.
