We give an account of various possible measurements in B physics for the collider experiments, CDF andDO&slash;,in the coming Tevatron Run II at Fermilab. This includes the measurements ofsin(2&bgr;)and other angles in the unitarity triangle related to the CKM matrix, which may lead to observation of CP violation outside the kaon system. Measurements of mass and lifetime differences, especially forBs,will be particularly interesting at Tevatron as this probably would not be studied in the present B factories. ©2000 American Institute of Physics.
