KHALED TEILAB IN COLLABORATION WITH SUSANNA GALLAS, FRANCESCO GIACOSA AND DIRK H. RISCHKE Meson production in proton-proton scattering within an eLSM

Outline The eLSM in the baryonic sector Results  pion-nucleon scattering length   production near threshold Summary Outlook

The eLSM in the baryonic sector for N f =2 The nucleon and its chiral partner (pseudo-) scalar & (axial-) vector mesons Chiral symmetry and dilatation invariance mirror assignment chirally symmetric mass term C. De Tar and T. Kunihiro, PRD 39 (1989) 2805)

Interaction of baryons with (pseudo-) scalar and (axial-) vector mesons The eLSM in the baryonic sector for N f =2 Details in S. Gallas et al. Phys.Rev. D82 (2010)

The mass of the nucleon parameterizes the contribution which does not stem from the quark condensate Details in S. Gallas, Francesco Giacosa and Dirk H. Rischke, Phys.Rev. D82 (2010)

pion-nucleon scattering length Mirror assignment and vector mesons are important to obtain this agreement large theoretical uncertainty due to the scalar- isoscalar sector

Baryonic Lagrangian with physical fields NO RESONANCE

pp → pp  near threshold no resonance References for data points in: F. Balestra et al. Phys. Rev. C, Vol. 63,

pp → pp  near threshold no resonance N(1535) N(1650)

pp → pp  near threshold m  =778 MeV m  =782 MeV m  =786 MeV NO RESONANCE m  =791 MeV m  =774 MeV

The eLSM with N f =2 ● spontaneous breaking of chiral symmertry ● ● non-physical mixing terms appear ● Solution: – shift of the axial vectors as: – renormalize the pseudoscalars as:

Black disk unitarization
