Abstract We investigate quantum entanglement in high-energy 2 → 2 scalar scattering, where the scalars are characterized by an internal flavor quantum number acting like a qubit. Working at the 1-loop order in perturbation theory, we build the fina

Abstract We revisit the dynamical generation of an arbitrarily small neutrino Yukawa coupling in the Standard Model with trans-Planckian asymptotic safety and apply the same mechanism to the gauged B − L model. We show that thanks to the presence o

Abstract The framework of trans-Planckian asymptotic safety has been shown to generate phenomenological predictions in the Standard Model and in some of its simple new physics extensions. A heuristic approach is often adopted, which bypasses the func

Abstract Motivated by the flavor anomalies in b → s transitions, we embed minimal models with a Z′ gauge boson, vector-like fermions, and a singlet scalar in the framework of trans-Planckian asymptotic safety. The presence of a fixed point in the

Abstract In gauge-Yukawa systems embedded in the framework of trans-Planckian asymptotic safety we discuss the dynamical generation of arbitrarily small Yukawa couplings driven by the presence of a non-interactive infrared-attractive fixed point in t

Abstract We perform a phenomenological analysis of simplified models of light, feebly interacting particles (FIPs) that can provide a combined explanation of the anomalies in b → sl + l − transitions at LHCb and the anomalous magnetic moment of t

Abstract We use the framework of asymptotically safe quantum gravity to derive predictions for scalar leptoquark solutions to the $$b\rightarrow s$$ b → s and $$b\rightarrow c$$ b → c flavor anomalies. The presence of an interactive UV fixed poin

Abstract We investigate solutions to the flavour anomalies in B decays based on loop diagrams of a “split” dark sector characterised by the simultaneous presence of heavy particles at the TeV scale and light particles around and below the B-meson

Abstract We present a Bayesian analysis of the implications for new physics in semileptonic $$b\rightarrow s$$ b→s transitions after including new measurements of $$R_K$$ RK at LHCb and new determinations of $$R_{K^*}$$ RK∗ and $$R_{K^{*+}}$$ RK

Abstract We provide an updated and improved study of the prospects of the H.E.S.S. and Cherenkov Telescope Array (CTA) experiments in testing neutralino dark matter in the Minimal Supersymmetric Standard Model with nine free parameters (p9MSSM). We i
