"Tau Vector and Axial Vector Spectral Functions in the Extended
Linear Sigma Model"

címmel tartandó szemináriumára.


The extended Linear Sigma Model (eLSM) describes scalar, pseudoscalar,
vector and axial-vector meson resonances, the glueball, and the
tetraquark, as well as baryons, on the basis of a Lagrangian that is
invariant under global chiral symmetry transformations and dilatation.
In addition, for N_F=2, we have now included the electroweak
interaction on the basis of a local SU(2)_L x U(1)_Y symmetry.
Thus we have all components available to compute the coherent amplitudes
that yield the vector and axial-vector spectral functions of the weak
tau-decay with intermediate a_1 and rho resonances. We
find that within the framework of the eLSM the assumption that the
rho and a_1 meson resonances are quarkonia and chiral
partners is valid. We will also see that the obtained weak spectral
functions give a nice illustration of Vector Meson Dominance in the weak
sector of meson vacuum phenomenology.
