The magnetic susceptibility in QCD
Claudio Bonati, Massimo D'Elia, Marco Mariti +2
Recently much work has been devoted to the study of QCD coupled to a background magnetic field. Strongly interacting matter acts as a magnetic medium and it is natural to study the…

Damir Becirevic, Goran Duplancic, Bruno Klajn +2
We compute the decay constants of the lowest ccbar-states with quantum numbers J(PC)=0(-+) [eta_c], 1(--) [J/psi], and 1(+-) [hc] by using lattice QCD and QCD sum rules. We conside…

Nuria Carrasco, Petros Dimopoulos, Roberto Frezzotti +6
We present the first results for the matrix elements of the operators describing neutral and mixing in the Standard Model and its extensions. The combination of…

We study the hadronic matrix elements describing the decay in and beyond the Standard Model. By using the twisted mass QCD on the lattice with …

We present an accurate lattice QCD computation of the b-quark mass, the B and Bs decay constants, the B-mixing bag-parameters for the full four-fermion operator basis, as well as e…
Magnetic susceptibility and equation of state of N_f = 2+1 QCD with physical quark masses
Claudio Bonati, Massimo D'Elia, Marco Mariti +2
We determine the free energy of strongly interacting matter as a function of an applied constant and uniform magnetic field. We consider N_f = 2+1 QCD with physical quark masses, d…
