Search for new particles in events with energetic jets and large missing transverse momentum in proton-proton collisions at $\sqrt{s} = $ 13 TeV

Armen Tumasyan, +2435 more
- 28 Jul 2021 - 
TL;DR: In this article, a search for new particles produced at the LHC in proton-proton collisions at 13 TeV was presented, using events with energetic jets and large missing transverse momentum.
Journal ArticleDOI

Measurement of the top quark mass using charged particles in pp collisions at s√=8 TeV

Khachatryan, +2265 more
- 18 May 2016 - 
TL;DR: In this paper, a novel technique for measuring the mass of the top quark that uses only the kinematic properties of its charged decay products is presented, where the main theoretical systematic uncertainties concerning the modeling of the fragmentation and hadronization of b quarks and the reconstruction of secondary vertices from the decays of b hadrons are studied.
Journal ArticleDOI

Search for dark matter produced in association with a leptonically decaying Z boson in proton-proton collisions at $\sqrt{s} =$ 13 TeV

Albert M. Sirunyan, +2410 more
- 11 Jan 2021 - 
TL;DR: In this paper, a search for dark matter particles is performed using events with a Z boson candidate and large missing transverse momentum at the LHC in 2016 and 2018, respectively.
