Specialized data-taking and data-processing techniques were introduced by the CMS
experiment in Run 1 of the CERN LHC to enhance the sensitivity of searches for new …

A new paradigm for data-driven, model-agnostic new physics searches at colliders is
emerging, and aims to leverage recent breakthroughs in anomaly detection and machine …

Abstract Particles beyond the Standard Model (SM) can generically have lifetimes that are
long compared to SM particles at the weak scale. When produced at experiments such as …

A bstract A search for new resonances decaying into a pair of jets is reported using the
dataset of proton-proton collisions recorded at\(\sqrt {s}\)= 13 TeV with the ATLAS detector at …

Following the updated measurement of the lepton flavour universality (LFU) ratio R_K RK in
B → K ℓ ℓ B→ K ℓ ℓ decays by LHCb, as well as a number of further measurements, eg R …

A bstract A search for narrow and broad resonances with masses greater than 1.8 TeV
decaying to a pair of jets is presented. The search uses proton-proton collision data at\(\sqrt …

A bstract We study constraints from causality and unitarity on 2→ 2 graviton scattering in four-
dimensional weakly-coupled effective field theories. Together, causality and unitarity imply …

A search for invisible decays of the Higgs boson as well as searches for dark matter
candidates, produced together with a leptonically decaying Z boson, are presented. The …

New light states thermally coupled to the Standard Model plasma alter the expansion history
of the Universe and impact the synthesis of the primordial light elements. In this work, we …

Searches for dijet resonances with sub-TeV masses using the ATLAS detector at the Large
Hadron Collider can be statistically limited by the bandwidth available to inclusive single-jet …
