Title: Enhancement of $Br (B_{d} \to μ^{+} μ^{-}) / Br (B_{s} \to μ^{+} μ^{-})$ in supersymmetric unified models

Abstract

We explain the 2.3σ deviation in the recent measurements of the neutral B meson decays into muon pairs from the standard model prediction in the framework of supersymmetric grand unified models using antisymmetric coupling as a new source of flavor violation. We show a correlation between the B_d→μ⁺μ⁻ decay and the CP phase in the B_d→J/ψK decay and that their deviations from the standard model predictions can be explained after satisfying constraints arising from various hadronic and leptonic rare decay processes, B-B¯, K-K¯ oscillation data, and electric dipole moments of electron and neutron. The allowed parameter space is typically represented by pseudoscalar Higgs mass m_A≤1 TeV and tanβ_H(≡v_u/v_d)≲20 for squark and gluino masses around 2 TeV.

Measurement of the Ratio of Branching Fractions $B (B_{c}^{+} \to J / ψ τ^{+} ν_{τ}) / B (B_{c}^{+} \to J / ψ μ^{+} ν_{μ})$

Journal Article Aaij, R. ; Adeva, B. ; Adinolfi, M. ; ... - Physical Review Letters

A measurement is reported of the ratio of branching fractions R(J/ψ) = B(B⁺_c → J/ψτ⁺ν_τ)/B(B⁺_c → J/ψμ⁺ν_μ), where the τ⁺ lepton is identified in the decay mode τ⁺ → μ⁺ν_μ¯ν_τ. This analysis uses a sample of proton-proton collision data corresponding to 3.0 fb^–1 of integrated luminosity recorded with the LHCb experiment at center-of-mass energies of 7 and 8 TeV. A signal is found for the decay B⁺_c → J/ψτ⁺ν_τ at a significance of 3 standard deviations corrected for systematic uncertainty, and the ratio of the branching fractions is measured to be R(J/ψ) = 0.71 ± 0.17 (stat) ± 0.18 (syst).more »« less

Measurement of the Ratio of the $B^{0} \to D^{* -} τ^{+} ν_{τ}$ and $B^{0} \to D^{* -} μ^{+} ν_{μ}$ Branching Fractions Using Three-Prong $τ$ -Lepton Decays

Journal Article Aaij, R. ; Adeva, B. ; Adinolfi, M. ; ... - Physical Review Letters

The ratio of branching fractions R(D*^–) ≡ B(B⁰ → D*^–τ⁺ν_τ)/B(B⁰ → D*^–μ⁺ν_μ) is measured using a data sample of proton-proton collisions collected with the LHCb detector at center-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb^–1. For the first time, R(D*^–) is determined using the τ-lepton decays with three charged pions in the final state. The B⁰ → D*^–τ⁺ν_τ yield is normalized to that of the B⁰ → D*^–π⁺π^–π⁺ mode, providing a measurement of B(B⁰ → D*^–τ⁺ν_τ)/B(B⁰ → D*^–π⁺π^–π⁺) = 1.97 ± 0.13 ± 0.18, where the first uncertainty is statistical and the secondmore »« less

Journal Article Dutta, Bhaskar ; Ghosh, Sumit ; Huang, Peisi ; ... - Physical Review D

Scenarios in which right-handed light Standard Model fermions couple to a new gauge group, U(1)_T3R, can naturally generate a sub-GeV dark matter candidate. But such models necessarily have large couplings to the Standard Model, generally yielding tight experimental constraints. We show that the contributions to g_u-2 from the dark photon and dark Higgs largely cancel out in the narrow window where all the experimental constraints are satisfied, leaving a net correction that is consistent with recent measurements from Fermilab. These models inherently violate lepton universality, and UV completions of these models can include quark flavor violation that can explain R_K(*)more »« less
