Event-Chain Monte Carlo for Yang-Mills SU(N) lattice field theory I : Design and proof of concept
Benoît Blossier, Manon Michel, Yacob Ozdalkiran
We develop two implementations of the Event-Chain Monte Carlo (ECMC) algorithm for Yang-Mills lattice gauge theories with the Wilson action. These algorithms consi…
The hadronic decay of vector charmonium
Benoît Blossier, Jochen Heitger, Jan Neuendorf +1
The extraction of decay parameters using lattice techniques is a computationally expensive task, requiring several volumes and group irreps to relate the spectrum on a lattice simu…
Hadronic decay of vector charmonium from the lattice
Benoît Blossier, Jochen Heitger, Jan Neuendorf +1
Estimating decay parameters in lattice simulations is a computationally demanding problem, requiring several volumes and momenta. We explore an alternative approach, where the tran…
The -meson leading-twist distribution amplitude
Benoît Blossier, Mariane Mangin-Brinet, José Manuel Morgado Chávez +1
In this project, we employ the short-distance factorization to compute the distribution amplitude of the -meson from Lattice QCD at leading twist. We employ a set of CLS $N_f=…
Lattice QCD extraction of the -meson -dependent parton distribution function
B. Blossier, C. Mezrag, J. M. Morgado Chávez +1
The formalism of short-distance factorization, conveyed through the pseudo-distribution approach, connects space-like and light-cone correlators and thus allows for the extraction…
The distribution amplitude of the -meson
Benoît Blossier, Mariane Mangin-Brinet, José Manuel Morgado Chávez +1
In this proceeding we determine the distribution amplitude of the -meson from first principles. This quantity appears as a consequence of factorization theorems, and it is nec…
The distribution amplitude of the -meson at leading twist from Lattice QCD
Benoît Blossier, Mariane Mangin-Brinet, José Manuel Morgado Chávez +1
Distribution amplitudes are functions of non-perturbative matrix elements describing the hadronization of quarks and gluons. Thanks to factorization theorems, they can be used to c…
The distribution amplitude of the meson
Miguel Teseo San José Pérez, Benoît Blossier, Mariane Mangin-Brinet +1
We report on the first lattice determination of the pseudoscalar meson light-cone distribution amplitude, using a set of three CLS ensembles at a pion mass $m_π \sim…
Decay constants of B-mesons from non-perturbative HQET with two light dynamical quarks
F. Bernardoni, B. Blossier, J. Bulava +8
We present a computation of B-meson decay constants from lattice QCD simulations within the framework of Heavy Quark Effective Theory for the b-quark. The next-to-leading order cor…
B-physics with Wilson fermions
F. Bernardoni, B. Blossier, J. Bulava +8
We report the final results of the ALPHA collaboration for some B-physics observables: , and . We employ CLS configurations with 2 flavors of improved Wi…
Efficient use of the Generalized Eigenvalue Problem
B. Blossier, G. von Hippel, T. Mendes +2
We analyze the systematic errors made when using the generalized eigenvalue problem to extract energies and matrix elements in lattice gauge theory. Effective theories such as HQET…
