Measurement of simplified template cross sections of the Higgs boson produced in association with W or Z bosons in the H→bb¯ decay channel in proton-proton collisions at s=13 TeV

A. Tumasyan, W. Adam, J. W. Andrejkovic, T. Bergauer et autres

Differential cross sections are measured for the standard model Higgs boson produced in association with vector bosons ( W , Z ) and decaying to a pair of b quarks. Measurements are performed within the framework of the simplified template cross sections. …

Search for medium effects using jets from bottom quarks in PbPb collisions at $\sqrt{sNN}$ =5.02 TeV

A. Tumasyan, W. Adam, J. W. Andrejkovic, T. Bergauer et autres

The first study of the shapes of jets arising from bottom (b) quarks in heavy ion collisions is presented. Jet shapes are studied using charged hadron constituents as a function of their radial distance from the jet axis. Lead-lead (PbPb) collision data …

Observation of Forward Neutron Multiplicity Dependence of Dimuon Acoplanarity in Ultraperipheral Pb-Pb Collisions at sNN=5.02 TeV

A. M. Sirunyan, A. Tumasyan, W. Adam, T. Bergauer et autres

The first measurement of the dependence of γγ→μ^{+}μ^{-} production on the multiplicity of neutrons emitted very close to the beam direction in ultraperipheral heavy ion collisions is reported. Data for lead-lead interactions at sqrt[s_{NN}]=5.02 TeV, with an integrated luminosity of approximately 1.5 …

Hard color-singlet exchange in dijet events in proton-proton collisions at s=13 TeV

A. M. Sirunyan, A. Tumasyan, W. Adam, F. Ambrogi et autres

Events where the two leading jets are separated by a pseudorapidity interval devoid of particle activity, known as jet-gap-jet events, are studied in proton-proton collisions at $\sqrt{s}=13\text{ }\text{ }\mathrm{TeV}$. The signature is expected from hard color-singlet exchange. Each of the highest transverse …

Study of dijet events with a large rapidity gap between the two leading jets in pp collisions at $$\sqrt{s}=7$$ $$\,\text {TeV}$$

A. M. Sirunyan, A. Tumasyan, W. Adam, E. Asilar et autres

of the second-leading jet and of the rapidity separation between the jets. The data are compared to previous measurements at the Tevatron, and to perturbative quantum chromodynamics calculations based on the Balitsky-Fadin-Kuraev-Lipatov evolution equations, including different models of the non-perturbative gap survival …
