Revisiting lifetimes of doubly charmed baryons

Lovro DulibiÄ, James Gratrex, BlaÅ¾enka MeliÄ +1

We present updated predictions for lifetimes of doubly charmed baryons, within the heavy quark expansion, including available NLO $I^\pm_{s}$ contributions and newly-computed terms in t…

Nonperturbative Parameters of Inclusive $I^_{b}$ Decays from Small Velocity Sum Rules

BlaÅ¾enka MeliÄ, Ivan NiÅ¡andÅ¾iÄ

We investigate the nonperturbative parameters entering the heavy quark expansion for the inclusive decay rates of the $I^_{b}$ baryon, focusing on the kinetic term $I^^¼_{I ¨} ^{2}$ and…

Revisiting the Higgs Boson Decay into a Photon and a Neutrino Pair

Aliaksei Kachanovich, Ivan NiÅ¡andÅ¾iÄ

We present new calculations of the leading-order one-loop amplitude and the decay rate for $H \to I^½ I^ˉ ½ I^^{3}$ within the standard model, employing reduction to a set of basic Passa…
