Estimates of the Weak Annihilation Contributions to the Decays $B \to \rho + \gamma$ and $B \to \omega + \gamma$ [PDF]

open access: yes, 1995
The dominant long-distance contributions to the exclusive radiative decays $B \to \rho (\omega) + \gamma$ involve photon emission from the light quarks at large distances, which cannot be treated perturbatively.

Exclusive B --> K^* l^+ l^-$ decay in the three Higgs doublet model [PDF]

open access: yes, 1999
We study the differential Branching ratio and CP asymmetry for the exclusive decay B --> K^* l^+ l^- in the three Higgs doublet model with additional global O(2) symmetry in the Higgs sector.

Towards a method for the objective assessment of cognitive workload: A pilot study in vessel traffic service (VTS) of maritime domain

open access: yesInternational Forum on Research and Technologies for Society and Industry Leveraging a better tomorrow, 2017
The complexity of traffic control systems, as well as the growing volume of traffic, interconnected missions types and mission demands on the operators, indicates that critical attention should still be paid to the problem of operator's cognitive ...

A Theoretical Reappraisal of Branching Ratios and CP Asymmetries in the Decays $B \to (X_d,X_s) \ell^+ \ell^-$ and Determination of the CKM Parameters [PDF]

open access: yes, 1998
We present a theoretical reappraisal of the branching ratios and CP asymmetries for the decays $ B \to X_q \ell^+ \ell^-$, with $q=d,s$, taking into account current theoretical uncertainties in the description of the inclusive decay amplitudes from the ...
