Nonlocal form factor of chromomagnetic penguin in B → Kℓ + ℓ − from QCD light-cone sum rules

open access: yesJournal of High Energy Physics
The branching fraction of the B → Kℓ + ℓ − decay has been measured recently by the LHC experiments, showing a deviation from theory predictions based on the Standard Model (SM).

High-pT LHC constraints on SMEFT operators affecting rare kaon and hyperon decays

open access: yesJournal of High Energy Physics
We consider the constraints on new physics affecting rare kaon and hyperon decay as parametrized by a low energy effective theory that can be obtained from high-pT observables at LHC. To this end, we match the relevant low energy Wilson coefficients onto

Leptonic meson decays into invisible ALP [PDF]

open access: yes, 2022
The theoretical calculation of pseudo–scalar leptonic decay widths into an invisible ALP, M→ℓνℓa, is reviewed. Assuming generic flavor–conserving ALP couplings to SM fermions and a generic ALP mass, ma, the latest experimental results for pseudo–scalar ...

Semi-leptonic decays of charmed baryons [PDF]

open access: yesNuclear 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.

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

open access: yesJournal 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 ...

CP violation in Semi-Leptonic τ decays

open access: yesAIP Conference Proceedings, 2007
We study CP violation in semi-leptonic $τ$ decays and we determine the conditions necessary to be able to define a observable CP asymmetry. We apply these conditions in both models, the standard model for the electroweak interactions and its supersymmetric extensions.

Top quark pair production and calorimeter energy resolution studies at a future collider experiment [PDF]

open access: yes, 2012
This thesis is focused on detector concepts and analyses investigated at a future linear electron positron collider. For precision measurements at such a collider, the CALICE collaboration develops imaging calorimeters, which are characterized by a fine ...

Partial next-to-next-to-leading-order corrections to the B → π form factors from light-cone sum rules

open access: yesJournal of High Energy Physics
By incorporating the available leading-power results at O α s $$ \mathcal{O}\left({\alpha}_s\right) $$ and next-to-leading-power corrections at tree level, we compute the O α s 2 β 0 $$ \mathcal{O}\left({\alpha}_s^2{\beta}_0\right) $$ contribution to the
