    Weak decays of $${\varvec{B}}_{{\varvec{c}}}$$ B c involving vector mesons in self-consistent covariant light-front approach by Thejus Mary S., Avijit Hazra, Neelesh Sharma, Rohit Dhir

    Published 2025-02-01
    “…The type-II correspondence in the CLF approach gives self-consistent results associated with the $$B^{(i)}_j$$ B j ( i ) functions, which vanish numerically after the replacement $$M^{\prime (\prime \prime )} \rightarrow M_0^{\prime (\prime \prime )}$$ M ′ ( ″ ) → M 0 ′ ( ″ ) in traditional type-I correspondence, and the covariance of the matrix elements is also restored. We investigate these effects on bottom-conserving $$B_c$$ B c to P(V) form factors that have not yet been studied in CLFQM type-II correspondence. …”

    Observation of a rare beta decay of the charmed baryon with a Graph Neural Network by The BESIII Collaboration

    Published 2025-01-01
    “…For the first time, the CKM matrix element $$\left\vert {V}_{cd}\right\vert$$ V c d is extracted via a charmed baryon decay as $$0.208\pm 0.01{1}_{{{{\rm{exp.}}}}}…”
