Abstract Axions and axion-like particles (ALPs) are well-motivated low-energy relics of high-energy extensions of the Standard Model (SM). We investigate the phenomenology of an ALP with flavor-changing couplings, and present a comprehensive analysis

Abstract We present an economical model where an S 1 leptoquark and an anomaly-free U(1) X gauge symmetry with X = B 3 − 2L μ /3 − L τ /3 are introduced, to account for the muon anomalous magnetic moment a μ ≡ (g μ − 2) and flavor puzzles

Abstract Vector-like quarks have been of interest for a plethora of experimentally motivated reasons and have come under increased investigation recently due to their inclusion to the Standard Model (SM) appreciably improving global fits to several f

Abstract We study a simplified model of flavoured Majorana dark matter in the Dark Minimal Flavour Violation framework. The model extends the Standard Model by a dark matter flavour triplet and a scalar mediator, through which the new dark fermions c

Abstract We develop an economical theoretical framework for combined explanations of the flavor physics anomalies involving muons: (g − 2) μ , R K ∗ $$ {R}_{K^{\left(\ast \right)}} $$ , and b → sμ + μ − angular distributions and branching

Abstract We analyze the class of models with an extra U(1) X gauge symmetry that can account for the b → sℓℓ anomalies by modifying the Wilson coefficients C 9e and C 9μ of the operators O 9 ℓ ≡ b ¯ γ μ P L s ℓ ¯ γ μ ℓ $$ {O}_{9\

Abstract We investigate the flavour alignment conditions that New Physics (NP) models need to satisfy in order to address the (g − 2) μ anomaly and, at the same time, be consistent with the tight bounds from μ → eγ and τ → μγ. We analyse

Abstract SND@LHC is an approved experiment equipped to detect scatterings of neutrinos produced in the far-forward direction at the LHC, and aimed to measure their properties. In addition, the detector has a potential to search for new feebly interac
