Grand Unified Theories (GUTs) are one of the most interesting high-energy completions of
the Standard Model, because they provide a rich, powerful and elegant group-theoretical …

Abstract The Standard Model of particles and fields describes the fundamental particles and
their interactions to high level of precision. The SM is nevertheless considered to be a low …

Algorithms used for the reconstruction and identification of electrons in the central region of
the ATLAS detector at the Large Hadron Collider (LHC) are presented in this paper; these …

A bstract Motivated by the recent LHCb announcement of a 3. 1σ violation of lepton-flavor
universality in the ratio RK= Γ (B→ Kμ+ μ−)/Γ (B→ Ke+ e−), we present an updated …

A search for the electroweak production of charginos and sleptons decaying into final states
with two electrons or muons is presented. The analysis is based on 139 fb\(^{-1}\) of proton …

The MEG experiment, designed to search for the μ^+ → e^+ γ μ+→ e+ γ decay, completed
data-taking in 2013 reaching a sensitivity level of 5.3 * 10^-13 5.3× 10-13 for the branching …

A search for the electroweak production of charginos and sleptons decaying into final states
with two electrons or muons is presented. The analysis is based on 139 fb $^{-1} $ of proton …

A bstract We present a thorough investigation of the vector leptoquark hypothesis for a
combined explanation of the B-physics anomalies. We analyze this hypothesis from a …

A bstract A search for new phenomena in events with two same-charge leptons or three
leptons and jets identified as originating from b-quarks in a data sample of 36.1 fb− 1 of pp …

We propose six new benchmark scenarios for Higgs boson searches in the Minimal
Supersymmetric Standard Model. Our calculations follow the recommendations of the LHC …
