Investigating non-local contributions in B s → ϕ ℓ ¯ ℓ $$ {B}_s\to \phi \overline{\ell}\ell $$ including higher-twist effects

Journal of High Energy Physics
We analyze the impact of higher-twist three-particle B s -meson light-cone distribution amplitudes (LCDAs) on the non-local form factors for the B s → ϕ ℓ ¯ ℓ $$ {B}_s\to \phi \overline{\ell}\ell $$ transition focusing on the ‘charm-loop’ contribution ...

Non-Leptonic Decays of Bileptons [PDF]

, 2021
We provide a detailed analysis of the decays of doubly-charged bilepton gauge bosons $Y^{\pm\pm}$, as predicted in models based on a $SU(3)_C\times SU(3)_L\times U(1)_X$ symmetry.

CP-violation in cascade decays at the LHC [PDF]

, 2010
We study the potential to observe CP-violating effects in various supersymmetric cascade decay chains at the LHC. Asymmetries composed by triple products of momenta of the final state particles are sensitive to CP-violating effects.

τ dipole moments via radiative leptonic τ decays [PDF]

, 2016
We propose a new method to probe the magnetic and electric dipole moments of the τ lepton using precise measurements of the differential rates of radiative leptonic τ decays at high-luminosity B factories.

Semi-leptonic decays of charmed baryons [PDF]

Nuclear Physics B, 1976
Abstract We present estimates of semi-leptonic decays of the charmed 1+ 2 baryons, members of the SU(3) 3∗ and 6 multiplets, into ordinary 1+ 2 and 3+ 2 baryons. We give general expressions for decay rates and the mass M(B+l) spectra.

Rare leptonic and semi-leptonic decays at LHCb [PDF]

Rare leptonic and semi-leptonic decays offer an excellent opportunity to test the Standard Model of Particle Physics. These proceedings report on two recent LHCb measurements. The first is an observation of the rare $J/\psi \to \mu^{+}\mu^{-}\mu^{+}\mu^{-

Radiative semileptonic decays of beautiful hadrons

Journal of High Energy Physics
We derive predictions for the hadronic matrix elements of radiative semileptonic decays of beautiful hadrons within Heavy Quark Effective Theory (HQET), relevant for future measurements at Belle II and LHCb.

Dispersive analysis of B → K (*) and B s → ϕ form factors

Journal of High Energy Physics, 2023
We propose a stronger formulation of the dispersive (or unitarity) bounds à la Boyd-Grinstein-Lebed (BGL), which are commonly applied in analyses of the hadronic form factors for B decays.

Charmless Non-Leptonic Multi-Body B decays [PDF]

, 2017
We review the theoretical and phenomenological status of two- and three-body charmless non- leptonic B decays, with an emphasis on factorization ...

Heavy quark symmetry behind b → c semileptonic sum rule

Journal of High Energy Physics
Lepton flavor universality violations in semileptonic b → c transitions have garnered attention over a decade. For $${R}_{{H}_{c}}={\text{BR}}\left({H}_{b}\to {H}_{c}\tau {\overline{\nu }}_{\tau }\right)/{\text{BR}}\left({H}_{b}\to {H}_{c}{\ell ...
