Abstract In view of both the latest LHCb measurement of R K ∗ $$ {R}_{K^{\left(\ast \right)}} $$ and the new 2.7σ deviation reported by Belle II on B + → K + ν ν ¯ $$ {B}^{+}\to {K}^{+}\nu \overline{\nu} $$ decays, we present a fit to the B m

The tension between measured W mass and its Standard Model prediction might arise from uncertainties in the hadronic contribution, and the same is true for the muon g − 2. Here, the authors show that such a common origin for the two anomalies is un

Abstract We investigate the extent to which perturbative calculations of the electroweak phase transition are arbitrary and uncertain, owing to their gauge, renormalisation scale and scheme dependence, as well as treatments of the Goldstone catastrop

Abstract We present an extension of the GM2Calc software to calculate the muon anomalous magnetic moment ( $${a_\mu ^{{\text {BSM}}}}$$ a μ BSM ) in the Two-Higgs Doublet Model. The Two-Higgs Doublet Model is one of the simplest and most popular ext

Abstract We present a likelihood analysis of the general two Higgs doublet model, using the most important currently measured flavour observables, in view of the anomalies in charged current tree-level and neutral current one-loop rare decays of B me

Abstract We introduce the GAMBIT Universal Model Machine (GUM), a tool for automatically generating code for the global fitting software framework GAMBIT, based on Lagrangian-level inputs. GUM accepts models written symbolically in FeynRules and SARA

Abstract We assess the status of a wide class of WIMP dark matter (DM) models in light of the latest experimental results using the global fitting framework GAMBIT. We perform a global analysis of effective field theory (EFT) operators describing the

Abstract The Fermilab Muon g −2 experiment recently reported its first measurement of the anomalous magnetic moment a μ FNAL $$ {a}_{\mu}^{\mathrm{FNAL}} $$ , which is in full agreement with the previous BNL measurement and pushes the world averag

Abstract The excess of electron recoil events seen by the XENON1T experiment has been interpreted as a potential signal of axion-like particles (ALPs), either produced in the Sun, or constituting part of the dark matter halo of the Milky Way. It has

Abstract We present a C++ software package called PhaseTracer for mapping out cosmological phases, and potential transitions between them, for Standard Model extensions with any number of scalar fields. PhaseTracer traces the minima of effective pote
