Recent COMPASS results and future prospects for ALICE

The COMPASS Collaboration has accumulated the world’s highest statistics on the reaction π− p → π+π−π− p at 190 GeV/c. The results, presented in Section 1, show that a new state JPC = 1++ state never reported before, the a1(1420), decaying to f0(980)π followed by f0(980) → ππ. In addition, the Colla...
