Tetraquark Spectroscopy: A Symmetry Analysis
J. Vijande, A. Valcarce
We present a detailed analysis of the symmetry properties of a four-quark wave function and its solution by means of a variational approach for simple Hamiltonians. We discuss seve…
Molecular and compact four-quark states
A. Valcarce, J. Vijande
We study charmonium (), bottomonium () and exotic ( and ) four-quark states by means of a standard non-relativisti…
Probabilities in nonorthogonal basis: Four--quark systems
J. Vijande, A. Valcarce
Four-quark states may exist as colorless meson-meson molecules or compact systems with two-body colored components. We derive an analytical procedure to expand an arbitrary four--q…
Exotic meson-meson molecules and compact four--quark states
J. Vijande, A. Valcarce, N. Barnea
We present an exact calculation of and wave states using different standard nonrelativistic quark--quark potentials. We explore in detail the charm and bot…
Screened potential and quarkonia properties at high temperatures
J. Vijande, G. Krein, A. Valcarce
We perform a quark model calculation of the quarkonia and spectra using smooth and sudden string breaking potentials. The screening parameter is sca…
Four-quark stability
J. Vijande, A. Valcarce, J. -M. Richard +1
The physics of charm has become one of the best laboratories exposing the limitations of the naive constituent quark model and also giving hints into a more mature description of m…
