New sets of CMS underlying-event parameters (“tunes”) are presented for the pythia 8 event
generator. These tunes use the NNPDF3. 1 parton distribution functions (PDFs) at leading …

We present the new version of OpenLoops, an automated generator of tree and one-loop
scattering amplitudes based on the open-loop recursion. One main novelty of OpenLoops 2 …

A new release of the Monte Carlo event generator Herwig (version 7.2) is now available.
This version introduces a number of improvements over the major version 7.0, notably: multi …

Measurements of both the inclusive and differential production cross sections of a top-quark–
antiquark pair in association with a Z boson (\(t {\bar {t}} Z\)) are presented. The …

A search for dark matter particles is performed using events with a Z boson candidate and
large missing transverse momentum. The analysis is based on proton–proton collision data …

This paper reports on a search for heavy resonances decaying into WW, ZZ or WZ using
proton–proton collision data at a centre-of-mass energy of s= 13 s= 13 TeV. The data …

A combination of searches for top squark pair production using proton–proton collision data
at a center-of-mass energy of 13\, Te V Te at the CERN LHC, corresponding to an integrated …

Measurements of t ̄ t H tt¯ H production in the H → b ̄ b H→ bb¯ channel depend in a
critical way on the theoretical uncertainty associated with the irreducible t ̄ t+ b tt¯+ b-jet …

We present a detailed study of Higgs boson production in association with a single top quark
at the LHC, at next-to-leading order accuracy in QCD. We consider total and differential …

This document presents the physics case and ancillary studies for the proposed CODEX-b
long-lived particle (LLP) detector, as well as for a smaller proof-of-concept demonstrator …
