New physics contributions to moments of inclusive b → c semileptonic decays
Inclusive semileptonic B →$ {X}_c\ell {\overline{\nu}}_{\ell } $ decays, where ℓ = μ, e, are by now standard candles in the determination of the CKM element |V$_{cb}$|. These determinations rely on the heavy-quark expansion and use moments of decay spectra to extract the non-perturbative parameters...
