چکیده

Properties and temperature behavior of π and σ bound states are studied in the framework of the nonlocal model with a separable interaction kernel based on the quark Dyson-Schwinger and the meson Bethe-Salpeter equations. Mπ(T ), fπ(T ), Mσ(T ) and Γσ→ππ(T ) are considered above and below the deconfinement and chiral restoration transitions.

We investigate the correlations between any number of arbitrarily far-apart regions of the vacuum of the free Klein-Gordon field by means of its finite duration coupling to an equal number of localized detectors. We show that the correlations between any N such regions enable us to distill an N-partite W state, and therefore exhibit true N-fold entanglement. Furthermore, we show that for N = 3,...

We report a project to study scalar particles by lattice QCD simulations. After a brief introduction of the current situation of lattice study of the sigma meson, we describe our numerical simulations of scalar mesons, σ and κ. We observe a low sigma mass, m π < m σ ≤ m ρ , for which the disconnected diagram plays an important role. For the kappa meson, we obtain higher mass than the experiment...

Despite the apparent simplicity of meson spectroscopy, light scalar mesons cannot be accommodated in the usual q ¯ q structure. We study the description of the scalar mesons below 2 GeV in terms of the mixing of a chiral nonet of tetraquarks with conventional q ¯ q states. A strong diquark-antidiquark component is found for several states. The consideration of a glueball as dictated by quenched...
