Probing the W tb vertex structure in t-channel single-top-quark production and decay in pp collisions at s = 8 $$ \sqrt{s}=8 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2017
To probe the W tb vertex structure, top-quark and W -boson polarisation observables are measured from t-channel single-top-quark events produced in proton-proton collisions at a centre-of-mass energy of 8 TeV.

Measurement of the differential and double-differential Drell-Yan cross sections in proton-proton collisions at root s=7 TeV [PDF]

open access: yes, 2013
Measurements of the differential and double-differential Drell-Yan cross sections are presented using an integrated luminosity of 4.5 (4.8) fb−1 in the dimuon (dielectron) channel of proton-proton collision data recorded with the CMS detector at the LHC ...

Matrix element regression with deep neural networks — Breaking the CPU barrier

open access: yesJournal of High Energy Physics, 2021
The Matrix Element Method (MEM) is a powerful method to extract information from measured events at collider experiments. Compared to multivariate techniques built on large sets of experimental data, the MEM does not rely on an examples-based learning ...

Search for doubly and singly charged Higgs bosons decaying into vector bosons in multi-lepton final states with the ATLAS detector using proton-proton collisions at s $$ \sqrt{\mathrm{s}} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2021
A search for charged Higgs bosons decaying into W ± W ± or W ± Z bosons is performed, involving experimental signatures with two leptons of the same charge, or three or four leptons with a variety of charge combinations, missing transverse momentum and ...

High Energy Hadron-hadron Collisions [PDF]

open access: yes, 1990
Results of a study on high energy collision with the geometrical model are summarized in three parts: (i) the elastic hadron-hadron collision, (ii) the inelastic hadron-hadron collision, and (iii) the e{sup +}e{sup {minus}} annihilation.

The emergence of multi-lepton anomalies at the LHC and their compatibility with new physics at the EW scale

open access: yesJournal of High Energy Physics, 2019
A recent study [1] has shown that a simplified model predicting a heavy scalar of mass 270 GeV (H ) that decays to a Standard Model (SM) Higgs boson in association with a scalar singlet of mass 150 GeV (S) can accommodate several anomalous multi-lepton ...
