In this paper, we provide evidence that Zn$$^{2+}$$ 2 + ions play a role in the SARS-CoV-2 virus strategy to escape the immune response mediated by the BST2-tetherin host protein. This conclusion is based on sequence analysis and molecular dynamics s

Using lattice simulations we demonstrate from first principles the existence of a non-perturbative mechanism for elementary particle mass generation in models with gauge fields, fermions and scalars, if an exact invariance forbids power divergent fer

In this paper we reexamine the possibility of extracting parton distribution functions from lattice simulations. We discuss the case of quasiparton distribution functions, the possibility of using the reduced Ioffe-time distributions and the more rec

We present physics results from simulations of QCD using Nf 1⁄4 2 dynamical Wilson twisted mass fermions at the physical value of the pion mass. These simulations are enabled by the addition of the clover term to the twisted mass quark action. We s

We show that a recent interesting idea to circumvent the difficulties with the continuation of parton distribution functions to the Euclidean region, that consists in looking at equal time correlators between proton states of infinite momentum, encou

We present a lattice QCD calculation of the up, down, strange and charm quark masses performed using the gauge configurations produced by the European Twisted Mass Collaboration with N f = 2 + 1 + 1 dynamical quarks, which include in the sea, besides

We present precise lattice computations for the $b$-quark mass, the quark mass ratios ${m}_{b}/{m}_{c}$ and ${m}_{b}/{m}_{s}$ as well as the leptonic $B$-decay constants. We employ gauge configurations with four dynamical quark flavors, up-down, stra

We show that in the massless N=1 supersymmetric Wess-Zumino theory it is possible to devise a computational strategy by which the x-space calculation of the ladder 4-point correlators can be carried out without introducing any regularization. As an a

We present unquenched lattice QCD results for the matrix elements of four-fermion operators relevant to the description of the neutral K and D mixing in the Standard Model and its extensions. We have employed simulations with Nf = 2 + 1 + 1 dynamical
