    In this contribution we consider the theoretical description of heavy meson-antimeson molecules from the effective field theory perspective. We are interested in the role of one pion exchange and heavy quark spin symmetry in the low energy description of the molecular states. We find that pion...

    We study the three-pion decays of the lightest isoscalar vector mesons, ω and ɸ, in a dispersive framework that allows for a consistent description of final-state interactions between all three pions. Our results are solely dependent on the phenomenological input for the pion-pion P-wave...

    A classical pion field that is similar to a disoriented chiral condensate is considered in the presence of an external source. The field is similar to the condensate in that the isotopic orientation of the field in the whole space is determined by a single vector. Within the nonlinear sigma...

  • Pseudoscalar meson mixing in effective field theory. Gedalin, E.; Moalem, A.; Razdolskaya, L. // AIP Conference Proceedings;2001, Vol. 603 Issue 1, p245 

    We show that for any effective field theory of colorless meson fields, the mixing schemes of particle states and decay constants are not only related but also determined exclusively by the kinetic and mass Lagrangian densities.

    An extended U(3)[sub L]... U(3)[sub R] chiral effective field theory which includes pseudoscalar and vector meson nonets as dynamic variables is presented. We combine the hidden symmetry approach with a general procedure of including the η' meson into chiral theory, and accounts for direct...

    Photoproduction of two neutral pions on a proton is considered. Qualitative analysis of the available experimental data demonstrates that a linear dependence of the total cross section on the energy testifies to the dominating contribution of s-waves for E < 800 MeV. Since in the tree...

    The mass differences between a charged pion and a neutral pion and between a charged kaon and a neutral kaon are calculated on the basis of a Higgs-type potential assigned to quarks. Moreover, an explanation is given for the mass spectrum of mesons. The results challenge the common view on...

    The renormalizable Kroll-Lee-Zumino field theory of pions and a neutral rho-meson is used to determine the scalar form factor of the pion in the space-like region at next-to-leading order. Perturbative calculations in this framework are parameter-free, as the masses and the rho-pion-pion...

    We review the present relativistic mean field theory from the view point of missing the contributions of pions. We discuss then the role played by pions for hadrons and light nuclei. We introduce the interesting experimental data on pionic states taken at RCNP. These data seem to suggest the...
