Sea quark QED effects and twisted mass fermions
Roberto Frezzotti, Giancarlo Rossi, Nazario Tantalo
We show that maximally twisted mass fermions can be employed to regularize on the lattice the fully unquenched QCD+QED theory with vanishing -term. We discuss how the critical m…
Isospin-0 s-wave scattering length from twisted mass lattice QCD
L. Liu, S. Bacchio, P. Dimopoulos +11
We present results for the isospin-0 s-wave scattering length calculated with Osterwalder-Seiler valence quarks on Wilson twisted mass gauge configurations. We use three $N_f…
Check of a new non-perturbative mechanism for elementary fermion mass generation
Stefano Capitani, Giulia Maria De Divitiis, Petros Dimopoulos +8
We consider a field theoretical model where a SU(2) fermion doublet, subjected to non-Abelian gauge interactions, is also coupled to a complex scalar field doublet via a Yukawa and…
Mass of the b-quark and B-decay constants from Nf=2+1+1 twisted-mass Lattice QCD
ETM Collaboration, A. Bussone, N. Carrasco +9
We present precise lattice computations for the b-quark mass, the quark mass ratios mb/mc and mb/ms as well as the leptonic B-decay constants. We employ gauge configurations with f…
A non-supersymmetric model with unification of electro-weak and strong interactions
Roberto Frezzotti, Marco Garofalo, Giancarlo Rossi
In this note we present an example of an extension of the Standard Model where unification of strong and electroweak interactions occurs at a level comparable to that occurring in…
