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 کاملRecoil Order Chiral Corrections to Baryon Octet Axial Currents
We calculate chiral corrections to the octet axial currents through O(p3) using baryon chiral perturbation theory (BCPT). The relativistic BCPT framework allows one to sum an infinite series of recoil corrections at a given order in the chiral expansion. We also include SU(3)-breaking operators occuring at O(p2) not previously considered. We determine the corresponding low-energy constants (LEC...
متن کاملChiral Structure in Baryon Magnetic Moments
The issue of chiral extrapolation has been highlighted as an important problem facing modern lattice QCD simulations [1,2], if one is to make any comparison with experiment. Extrapolations in quark mass are nontrivial because of nonanalytic contributions which arise as a consequence of dynamically broken chiral symmetry in the QCD vacuum [3]. At typical lattice quark masses there is little evid...
متن کاملBaryon Structure and the Chiral Symmetry of QCD
Beyond the spontaneous chiral symmetry breaking scale light and strange baryons should be considered as systems of three constituent quarks with an effective confining interaction and a chiral interaction that is mediated by the octet of Goldstone bosons (pseudoscalar mesons) between the constituent quarks.
متن کامل0 Chiral aspects of baryon structure in the quark model
The implications of chiral symmetry for the quark model are discussed. In particular its connection with the meson-baryon approach is outlined. It is stressed that in the closure approximation, where the intermediate baryon states are used instead of the original quark basis, it is imperative to take into account the whole infinite tower of the radially excited states in order that the cruciall...
