A search for exotic decays of the Higgs boson into a pair of spin-zero particles, H → aa, where the a-boson decays into b-quarks promptly or with a mean proper lifetime cτa up to 6 mm and has a mass in the range of 20–60 ...

A search for new heavy particles that decay into top-quark pairs is performed using data collected from proton–proton collisions at a centre-of-mass energy of 13 TeV by the ATLAS detector at the Large Hadron Collider. The ...

This Letter presents a search for exotic decays of the Higgs boson to a pair of new (pseudo)scalar particles, H → aa, where the a particle has a mass in the range 20–60 GeV, and where one of the a bosons decays into a pair ...

A search for a heavy neutral Higgs boson, A, decaying into a Z boson and another heavy Higgs boson, H, is performed using a data sample corresponding to an integrated luminosity of 36.1 fb−1 from proton– proton collisions ...

The observation of Higgs boson production in association with a top quark pair (tt H¯ ), based on the analysis of proton–proton collision data at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the ...

A measurement of the fragmentation functions of jets into charged particles in p + Pb collisions and pp collisions is presented. The analysis utilizes 28 nb−1 of p + Pb data and 26 pb−1 of pp data, both at √sNN= 5.02 TeV, ...

Studies of antimatter are important for understanding our universe at a fundamental level. There are still unsolved problems, such as the matter-antimatter asymmetry in the universe. The AEgIS experiment at CERN aims at ...

This paper presents combinations of inclusive and differential measurements of the charge asymmetry (AC) in top quark pair (t¯t) events with a lepton+jets signature by the ATLAS and CMS Collaborations, using data from LHC ...

A search is performed for new phenomena in events having a photon with high transverse momentum and a jet collected in 36.7 fb−1 of proton–proton collisions at a centre-of-mass energy of √s = 13 TeV recorded with the ATLAS ...

A search is presented for photonic signatures, motivated by generalized models of gauge-mediated supersymmetry breaking. This search makes use of proton-proton collision data at ffiffi s p ¼ 13 TeV corresponding to an ...
