Ghost-gluon coupling, power corrections and Ams from lattice QCD with a dynamical charm
Blossier, B.; Boucaud, Ph.; Brinet, M.; Soto Borrero, Feliciano Carlos de; Du, X.; Gravina, M.; Morenas, V.; Pène, O.; Petrov, K.; Rodríguez Quintero, José
(American Physical Society, 2012)
We present results concerning the nonperturbative evaluation of the ghost-gluon running QCD coupling constant from Nf=2 twisted-mass lattice calculations. A novel method for calibrating the lattice spacing, independent of ... -
High statistics determination of the strong coupling constant in Taylor scheme and its OPE Wilson coe cient from lattice QCD with a dynamical charm
Blossier, B.; Boucaud, Ph.; Brinet, M.; Soto Borrero, Feliciano Carlos de; Morenas, V.; Pène, O.; Petrov, K.; Rodríguez Quintero, José (American Physical Society, 2014)
This paper reports on the determination of S from lattice simulations with 2+1+1 twisted-mass dynamical avours via the computation of the ghost-gluon coupling renormalized in the MOM Taylor scheme. A high-statistics ... -
Novel method for the physical scale setting on the lattice and its application to Nf=4 simulations
Blossier, B.; Boucaud, Ph.; Brinet, M.; Soto Borrero, Feliciano Carlos de; Morenas, V.; Pène, O.; Petrov, K.; Rodríguez Quintero, José (American Physical Society, 2014)
This paper reports on a new procedure for the lattice spacing setting that takes advantage of the very precise determination of the strong coupling in the Taylor scheme. Although it can be applied for the physical scale ... -
Renormalization of quark propagators from twisted-mass lattice QCD at N-f=2
Blossier, B.; Boucaud, Ph.; Brinet, M.; Soto Borrero, Feliciano Carlos de; Liu, Z.; Morenas, V.; Pène, O.; Petrov, K.; Rodríguez Quintero, José (American Physical Society, 2011)
We present results concerning the nonperturbative evaluation of the renormalization constant for the quark field, Z(q), from lattice simulations with twisted-mass quarks and three values of the lattice spacing. We use the ... -
Strong Running Coupling at τ and Z 0 Mass Scales from Lattice QCD
Blossier, B.; Boucaud, Ph.; Brinet, M.; Soto Borrero, Feliciano Carlos de; Du, X.; Morenas, V.; Pène, O.; Petrov, K.; Rodríguez Quintero, José (American Physical Society, 2012)
This Letter reports on the first computation, from data obtained in lattice QCD with u, d, s, and c quarks in the sea, of the running strong coupling via the ghost-gluon coupling renormalized in the momentum-subtraction ... -
Testing OPE for ghosts, gluons and αs
Petrov, K.; Blossier, B.; Pène, O.; Rodríguez Quintero, José (Sissa Medialab, 2012-10)
We present here our results on extracting Wilson coefficients from different quantities such as ghost and gluon propagators which are calculated by means of Lattice QCD. The results confirm the validity of our method for ... -
Testing the OPE Wilson coefficient for A2 from lattice QCD with a dynamical charm
Blossier, B.; Boucaud, Ph.; Brinet, M.; Rodríguez Quintero, José (American Physical Society, 2014-05)
Gluon and ghost propagators data, obtained in Landau gauge from lattice simulations with two light and two heavy dynamical quark flavours (Nf=2+1+1), are described here with a running formula including a four-loop ...
