The new physics reach of null tests with $$D \rightarrow \pi \ell \ell $$ and $$D_s \rightarrow K \ell \ell $$ decays

$$|\Delta c|=|\Delta u|=1$$ processes are unique probes of flavor physics in the up-sector within and beyond the Standard Model (SM). SM tests with rare semileptonic charm meson decays are based on

Prospects of discovering new physics in rare charm decays

The LHCb bounds on the branching ratio of the rare decay $$D^0 \rightarrow \mu ^+ \mu ^-$$D0→μ+μ- and the constraints on the branching ratio of $$D^+ \rightarrow \pi ^+ \mu ^+ \mu ^-$$D+→π+μ+μ- in

Rare $$\Lambda _c\rightarrow p \ell ^+\ell ^-$$Λc→pℓ+ℓ- decay in the relativistic quark model

The relativistic quark model based on the quasipotential approach with the QCD-motivate potential is employed for the calculation of the form factors of the $$\Lambda _c\rightarrow p$$Λc→p rare weak

Probing for new physics with rare charm baryon (Λc, Ξc, Ωc) decays

Abstract We analyze rare charm baryon decays within the standard model and beyond. We identify all null test observables in unpolarized Λc→ pℓ+ℓ−, ℓ = e, μ decays, and study the new physics

Light cone QCD sum rules study of the semileptonic heavy ΞQ and Ξ′Q transitions to Ξ and Σ baryons

The semileptonic decays of heavy spin-1/2, Ξb(c) and Ξ′b(c) baryons to the light spin-1/2, Ξ and Σ baryons are investigated in the framework of light cone QCD sum rules. In particular, using the most
