QCD corrections at subleading power for inclusive nonleptonic decays
Thomas Mannel, Daniel Moreno, Alexei A. Pivovarov
In this paper we compute the NLO QCD corrections for the inclusive nonleptonic decay rates of -hadrons at subleading power of the heavy quark expansion. In particular, we discus…
The Heavy Quark Expansion for the Charm Quark
Th. Mannel, D. Moreno, A. A. Pivovarov
We show that one can re-arrange the Heavy Quark Expansion for inclusive weak decays of charmed hadrons in such a way that the resulting expansion is an expansion in $Λ_{\rm QCD} /…
Completing corrections to non-leptonic bottom-to-up-quark decays
Daniel Moreno Torres
We compute the contributions of dimension six two-quark operators to the non-leptonic decay width of heavy hadrons due to the flavor changing bottom-to-up-quark transition in the h…
S-wave heavy quarkonium spectrum with next-to-next-to-next-to-leading logarithmic accuracy
C. Anzai, D. Moreno, A. Pineda
We obtain the Potential NRQCD Lagrangian relevant for S-wave states with next-next-to-next-to-leading logarithmic (NNNLL) accuracy. We compute the heavy quarkonium mass of spin-ave…
P-wave heavy quarkonium spectrum with next-to-next-to-next-to-leading logarithmic accuracy
Clara Peset, Antonio Pineda, Jorge Segovia
We compute the heavy quarkonium mass of (angular momentum) states, with otherwise arbitrary quantum numbers, with next-next-to-next-to-leading logarithmic (NLL) accu…
Spectator effects in the HQET renormalization group improved Lagrangian at with leading logarithmic accuracy: Spin-dependent case
Daniel Moreno
The present paper incorporates the effects induced by massless spectator quarks in the renormalization group improved Wilson coefficients associated to the spin-d…
