Abstract
The large data sample recorded with the Belle detector at the Y(5S) energy provides a unique opportunity to study the poorly-known meson. Two analyses, performed with a data sample representing an integrated luminosity of 121 /fb, are presented: the measurement of the Bs0->J/psi f0(980) and Bs0->J/psi f0(1370) branching fractions, and the 5sigma observation of the decay Bs0-bar->Lambda(c)+ pi- Lambda-bar which is the first observation of a baryonic Bs0 decay. In addition, we present new results of a measurement of the CKM angle phi_1(beta) with B pi tagged events.
