$$B\rightarrow K^*\mu ^+\mu ^-$$ B → K ∗ μ + μ - optimised observables in the MSSM

“…The excess of these decays can each be individually described in the type-II 2HDM. However, when combined, theB →D ( * ) τ −ν τ decays exclude the type-II 2HDM charged boson at 99.8 % confidence level for any value of tan β/m H + [62,63]. The MSSM contributions to these two flavour changing charged current processes are also completely dominated by the exchange of a charged Higgs boson, leading to a pattern very similar to that of the type-II 2HDM.…”

“…Other observables in tension with the SM are the excess of B →Dτ −ν τ andB →D * τ −ν τ decays observed by the BaBar collaboration [62]. The excess of these decays can each be individually described in the type-II 2HDM.…”

“…We have assumed that potential right-handed neutrino fields (sterile with respect to the SM gauge group) are heavy compared to the low-energy scale and have been integrated out of the low-energy effective theory. 1 If the NP is coming from dynamics at Λ v and electroweak symmetry breaking is linearly realized, then an effective SU (2) L ×U (1) Y invariant effective theory applies [41,43]. A non-trivial consequence of this is that, at leading order in the matching between the high-and low-energy theories [26]:…”

“…Moreover, in the SM, due to lepton universality (LU), the meson decays involving the same hadronic final states and different generation leptonics are expected to have the same BF with uncertainty [11][12][13][14][15][16]. Recently, independent hints of violation in LU have been observed in the SL decays B → D ðÃÞ l þ ν l (l ¼ e, μ or τ) [17][18][19][20][21][22] and B ðsÞ → K ðÃÞ ðϕÞl þ l − (l ¼ e or μ) [23][24][25][26]. Any violation of LU may be induced by new physics beyond the SM [14][15][16].…”
