Searches for supersymmetry based on events with b jets and four W bosons in pp collisions at 8 TeV

Vardan Khachatryan, +2138 more
- 18 May 2015 - 
TL;DR: In this paper, five mutually exclusive searches for supersymmetry are presented based on events in which b jets and four W bosons are produced in proton-proton collisions at sqrt(s) = 8 TeV.
Journal ArticleDOI

Search forBs0→μ+μ−andB0→μ+μ−Decays inppCollisions ats=7TeV

S. Chatrchyan, +2233 more
- 01 Nov 2011 - 
TL;DR: In this article, a search for the rare decays was performed in collisions at the LHC with a data sample corresponding to an integrated luminosity of $1.14, and the resulting upper limits on the branching fractions were shown to be l1.9 and l4.6 at 95% confidence level.
Journal ArticleDOI

Evidence for an involvement of mu-, but not delta- or kappa-opiate receptors in sympathetically and parasympathetically mediated cardiovascular responses to opiates upon anterior hypothalamic injection

Andreas Pfeiffer, +3 more
- 01 Sep 1982 - 
TL;DR: Mu-, but not delta- or kappa opiate receptors mediate the cardiovascular effects of opiates upon microinjection into the anterior hypothalamus of awake rats, and high doses cause a pronounced respiratory depression which partly counteracts the sympathetically induced cardiovascular stimulation.
Journal ArticleDOI

Measurement of the ZZ production cross section and Z → ℓ+ℓ−ℓ′+ℓ′− branching fraction in pp collisions at s=13 TeV

Vardan Khachatryan, +2292 more
- 29 Jul 2016 - 
TL;DR: In this article, four-lepton production in proton-proton collisions was studied at a center-of-mass energy of 13 TeV with the CMS detector at the LHC.
Journal ArticleDOI

Search for direct pair production of supersymmetric partners to the τ lepton in proton–proton collisions at √s=13TeV

Albert M. Sirunyan, +2309 more
- 02 Mar 2020 - 
TL;DR: A search is presented for τ slepton pairs produced in proton-proton collisions at a center-of-mass energy of 13 TeV in events containing two τ leptons in the final state, on the assumption that eachτ slepton decays primarily to a τ lepton and a neutralino.
