Mixing of scalar tetraquark and quarkonia states in a chiral approach
A chiral invariant Lagrangian describing the tetraquark-quarkonia interaction is considered at the leading and subleading order in the large-Nc expansion. Spontaneous chiral symmetry breaking generates mixing of scalar tetraquark and quarkonia states and non-vanishing tetraquark condensates. In particular, the mixing strength is related to the decay strengths of tetraquark states into pseudosca...
متن کاملChiral Transition in QCD and Scalar Correlations
We review recent developments in exploring possible precursory phenomena of partial restoration of chiral symmetry in nuclear medium by examining the spectral function in the scalar channel. We emphasize that the wave function renormalization of the pion in the medium plays an essential role to induce the decrease of the pion decay constant as the order parameter of chiral transition. We also s...
متن کاملScalar Quarkonium and the Scalar Glueball
The identification of fJ(1710) as the lightest scalar glueball is supported at present by two different sets of calculations. For the valence approximation to the infinite volume continuum limit of the lightest scalar glueball mass, a calculation on GF11 [1], using 25000 to 30000 gauge configurations, gives 1740 ± 71 MeV. An independent calculation by the UKQCD-Wuppertal [2] collaboration, usin...
