Renormalon-based resummation for B(D) Mesons
Cesar Ayala, Gorazd Cvetic
We apply a previously developed method of renormalon-based resummation of spacelike and timelike QCD observables, to evaluate of the values of the pole masses of and $c…
The chromomagnetic moment of a heavy quark with hyperasymptotic precision
Cesar Ayala, Antonio Pineda
We determine the normalization of the leading infrared renormalon of the chromomagnetic moment of a heavy quark. Estimates of higher order coefficients of the perturbative series a…
Extraction of using Borel-Laplace sum rules for tau decay data
César Ayala, Gorazd Cvetič, Diego Teca
Double-pinched Borel-Laplace sum rules are applied to ALEPH -decay data. For the leading-twist () Adler function a renormalon-motivated extension is used, and the 5-loop co…
Determination of perturbative QCD coupling from ALEPH decay data using pinched Borel-Laplace and Finite Energy Sum Rules
Cesar Ayala, Gorazd Cvetic, Diego Teca
We present a determination of the perturbative QCD (pQCD) coupling using the V+A channel ALEPH -decay data. The determination involves the double-pinched Borel-Laplace Sum Rules…
Hyperasymptotic approximation to the plaquette and determination of the gluon condensate
Cesar Ayala, Xabier Lobregat, Antonio Pineda
We give the hyperasymptotic expansion of the plaquette with a precision that includes the terminant associated to the leading renormalon. Subleading effects are also considered. Th…
Evaluation of neutrinoless double beta decay: QCD running to sub-GeV scales
Cesar Ayala, Gorazd Cvetic, Lorena Gonzalez
We evaluate QCD effects in the neutrinoless double beta () decay, originating from new physics short-range mechanism in the form of five dimension-9 operators. For this, we e…
