Workshop for young scientists with research interests focused on physics at FAIR

Using the U(3)R x U(3)L extended Linear Sigma Model (eLSM) with ordinary mesonic degrees of freedom and glueballs we calculate decay widths in order to study their vacuum interactions at low energy and in particular the nature of the resonances f0(1370), f0(1500) and f0(1710). In this context the understanding of the mixing behaviour in the scalar-isoscalar sector is essential.
