Effective field theory analysis of rare |∆c| = |∆u| = 1 charm decays

Journal of High Energy Physics
We perform a global analysis of |∆c| = |∆u| = 1 transitions using recent data on D 0 → μ + μ − , D + → π + μ + μ − , Λ c → p μ + μ − , and D 0 → π + π − μ + μ − decays, and work out constraints on new physics Wilson coefficients C 7 , 9 , 10 ′ $$ {C}_{7 ...

Testing lepton flavor universality at the Electron-Ion Collider

Journal of High Energy Physics
Measurements of b → cτ − ν ¯ τ $$ b\to {c\tau}^{-}{\overline{\nu}}_{\tau } $$ transitions at colliders are highly motivated for testing lepton flavor universality (LFU), a cornerstone hypothesis of the Standard Model (SM).

Radiative corrections to the muon polarization in the semileptonic decay of a neutral kaon

Journal of High Energy Physics
A model-independent expression for the Dalitz plot of the semileptonic decays of a neutral kaon K μ 3 0 $$ {K}_{\mu 3}^0 $$ , including radiative corrections to order O $$ \mathcal{O} $$ [(α/π)(q/M 1)], where q is the four-momentum transfer and M 1 is ...

Disentangling left-handed and right-handed neutrino effects in B c → τ ν ¯ τ $$ {B}_c\to \tau {\overline{\nu}}_{\tau } $$ decay

Journal of High Energy Physics
Inspired by the anomalies in B → D ∗ τ ν ¯ τ $$ B\to {D}^{\left(\ast \right)}\tau {\overline{\nu}}_{\tau } $$ decay, in this work, we carefully study the influence of the most general dimension-six effective operators involving right-handed neutrinos on ...

An imperative study of the angular observables in Λ b → Λ c + → Λ π + ℓ − ν ¯ ℓ $$ {\Lambda}_b\to {\Lambda}_c^{+}\left(\to \Lambda {\pi}^{+}\right){\ell}^{-}{\overline{\nu}}_{\ell } $$ decay and probing the footprint of new physics

Journal of High Energy Physics
We study the four-fold angular distribution of the semileptonic Λ b → Λ c + → Λ π + ℓ − ν ¯ ℓ $$ {\Lambda}_b\to {\Lambda}_c^{+}\left(\to \Lambda {\pi}^{+}\right){\ell}^{-}{\overline{\nu}}_{\ell } $$ decay and find out analytical expressions for various ...
