Lattice QCD and QCD sum rule determination of the decay constants of ηc, J/ψ and hc states
Abstract We compute the decay constants of the lowest c c ¯ -states with quantum numbers J P C = 0 − + ( η c ), 1 − − ( J / ψ ), and 1 + − ( h c ) by using lattice QCD and QCD sum rules. We considerExpand

Leading isospin breaking effects on the lattice
We present a method to evaluate on the lattice the leading isospin breaking effects due to both the small mass difference between the up and down quarks and the QED interaction. Our proposal isExpand

Recent progress on QCD inputs for axion phenomenology
The properties of the QCD axion are strictly related to the dependence of strong interactions on the topological parameter theta. We present a determination of the topological properties of QCD forExpand

Leading isospin-breaking corrections to pion, kaon and charmed-meson masses with Twisted-Mass fermions
We present a lattice computation of the isospin-breaking corrections to pseudoscalar meson masses using the gauge configurations produced by the European Twisted Mass collaboration with $N_f = 2 + 1Expand

QCD phase diagram in a magnetic background for different values of the pion mass
We investigate the behavior of the pseudo-critical temperature of $N_f = 2+1$ QCD as a function of a static magnetic background field for different values of the pion mass, going up to $m_\pi \simeqExpand

Order of the Roberge-Weiss endpoint (finite size transition) in QCD
We consider the endpoint of the Roberge-Weiss (RW) first order transition line present for imaginary baryon chemical potentials. We remark that it coincides with the finite size transition relevantExpand

First Lattice Calculation of the QED Corrections to Leptonic Decay Rates.
The leading-order electromagnetic and strong isospin-breaking corrections to the ratio of K_{μ2} and π_{μ2} decay rates are evaluated for the first time on the lattice, following a method recentlyExpand
