Probing effects of new physics in Ab0 → Ac+ μ-μ(v)over-barμ

We present, for the first time, the six-fold differential decay density expression for Ag Ac+f Ft, taking into account the polarisation of the Ag baryon and a complete basis of new physics operators. Using the expected yield in the current dataset collected at the LHCb experiment, we present sensitivity studies to determine the experimental precision on the Wilson coefficients of the new physics operators with Ai Ac+p Fit decays in two scenarios. In the first case, unpolarised Ab -+ AG-Fit Fit decays with Ac pK+7 are considered, whereas polarised Al) Ac+p Fit decays with Ac piq) are studied in the second. For the latter scenario, the experimental precision that can be achieved on the determination of Ai polarisation and Ac weak decay asymmetry parameter is also presented.
