The A1 meson problem

Description
The A1 is currently seen as a threshold enhancement of the (rho0π+-) system in the π+-p→rho0π+-p reactions. It is produced diffractively, and its production mechanism can be well explained by the Deck model which implies the A1 not being a resonance. In cluster analyses the A1 is found to be a low mass cluster which is characterized by the strong pion exchange coupling within the (3π)+- systems. The A1 has not been seen in charge exchange reactions and annihilation-type reactions
