On the impact of meson mixing on Bs→ ϕee angular observables at low q2

A bstract Decays based on the b → sγ transition are expected to yield left-handed photons in the Standard Model, but could be particularly sensitive to New Physics contributions modifying the short-distance Wilson coefficients C 7 and C 7′ defined in the low-energy Effective Field Theory. These coef...
