2010/3/16
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...

Rise and Fall of Pentaquarks in the QCD Sum Rules Approach
Mass and decay Pentaquarks QCD Sum Rules
2010/10/13
We review the existing mass and decay width determinations of pentaquarks with QCD Sum Rules (QCDSR). We give special attention to the intermediate assumptions and choices which we are obliged to do i...
