We present measurements of the masses and widths of four bottom baryon resonances, S ()±
b ,reconstructed in the L0 bp± hadron decay modes.
The masses of the heavy tetraquarks with open charm and bottom are calculated within the diquark-antidiquark picture in the framework of the relativistic quark model.
A general introduction is given to what can be predicated about quantum gravity once the lessons from the standard model of particle physics are taken into account.
Strong coupling，charm- and bottom-quark masses from electron-positron annihilation
strong coupling quark masses
2010/5/7
The cross section for electron-positron annihilation into hadrons allows for a precise determination of the strong coupling constant and the charm- and bottom-quark masses. Recent theoretical and expe...

Baryons of the type Qqqqq-bar (where Q = c,b and q = u,d,s quarks) forming anti-decapenta (15)-plets with spin-parity one half-plus are predicted on simple theoretical considerations. The lightest mem...
We search for new charmless decays of neutral $b$--hadrons to pairs of charged hadrons with the upgraded Collider Detector at the Fermilab Tevatron. Using a data sample corresponding to 1 fb$^{-1}$ of...
