Comparison of the Z/γ ∗ + jets to γ + jets cross sections in pp collisions at √s= 8 TeV

Vardan Khachatryan, +2287 more
- 20 Oct 2015 - 
TL;DR: In this paper, a comparison of the differential cross sections for the processes Z/gamma* + jets and photon (gamma) + jets is presented based on data collected with the CMS detector at sqrt(s) = 8 TeV corresponding to an integrated luminosity of 19.7 inverse femtobarns.
Proceedings ArticleDOI

Merging Nonlinear Optics and Negative-Index Metamaterials

Andrey Popov, +1 more
- 03 Aug 2011 - 
TL;DR: In this article, the extraordinary properties of nonlinear optical propagation processes in double-domain positive/negative index metamaterials are reviewed and the possibilities for creating unique ultracompact photonic devices such as data processing chips and nonlinear-optical sensors are shown.
Journal ArticleDOI

Search for direct pair production of scalar top quarks in the single- and dilepton channels in proton-proton collisions at √s= 8 TeV

Vardan Khachatryan, +2365 more
- 09 Feb 2016 - 
TL;DR: In this article, a search for the top squark t_1, the lighter of the two supersymmetric partners of the top quark, is reported from a search of 19.7 fb^(−1) of proton-proton collisions at √s = 8 TeV collected with the CMS detector at the LHC.
Journal ArticleDOI

Observation of a New Excited Beauty Strange Baryon Decaying to Ξb- π+π-

Albert M. Sirunyan, +2345 more
- 25 Jun 2021 - 
TL;DR: In this article, an event sample of proton-proton collisions at 13 TeV was collected by the CMS experiment at the LHC in 2016-2018 and corresponding to an integrated luminosity of 140 fb$^{-1}.
Journal ArticleDOI

Investigation into the event-activity dependence of ϒ(nS) relative production in proton-proton collisions at √ s = 7 TeV

Albert M. Sirunyan, +2379 more
- 02 Nov 2020 - 
TL;DR: In this article, the production cross sections between excited ϒ(2S) and ϒ (3S) mesons and the ground state, detected via their decay into two muons, are studied as a function of the number of charged particles in the event.
