Charmonium radiative transitions to dileptons from lattice QCD: The case of $h_{c} \to I^\cdot_{c} ℓ^{+} ℓ^{-}$ and $I ¨ _{c 1} \to J / I ¨ ℓ^{+} ℓ^{-}$

D. BeÄireviÄ, R. Di Palma, R. Frezzotti +4

We present a lattice QCD study of dilepton production in charmonium transitions, specifically focusing on the $1^{+-} \to 0^{-+}$ and $1^{++} \to 1^{--}$ processes: $h_c \to Î·_c \…

Kaon radiative leptonic decay rates from lattice QCD simulations at the physical point

R. Di Palma, R. Frezzotti, G. Gagliardi +6

We present a lattice QCD calculation of the radiative leptonic decay rates of the kaon, improving upon our previous work, arXiv:2006.05358. Our analysis uses gauge ensembles genera…

Lattice QCD study of the $I ¨ _{c 1} \to J / I ¨ I^^{3}$ decay

D. BeÄireviÄ, R. Di Palma, R. Frezzotti +4

We present the results of our lattice QCD computation of the electric ( $E_{1}$ ) and magnetic $(M_{2})$ form factors relevant to the $I ¨ _{c 1} \to J / I ¨ I^^{3}$ decay by using the gauge f…

Global analysis of charm mixing parameters and determination of the CKM angle $I^^{3}$

F. Betti, M. Bona, M. Ciuchini +9

We present an updated global analysis of beauty decays sensitive to the angle $I^^{3}$ of the Cabibbo-Kobayashi-Maskawa matrix and of $D$ -meson mixing data in the framework of approxim…

Lattice QCD determination of the radiative decay rates $h_{c} \to I^\cdot_{c} I^^{3}$ and $h_{b} \to I^\cdot_{b} I^^{3}$

D. BeÄireviÄ, R. Di Palma, R. Frezzotti +4

We present the results of our lattice QCD computation of the hadronic matrix elements relevant to the $h_{c} \to I^\cdot_{c} I^^{3}$ and $h_{b} \to I^\cdot_{b} I^^{3}$ decays by using the gauge configur…
