A New QCD Correction to Gauge Boson Decay into Heavy Flavor
Yu Jia
We find that, at order alpha_s, the partial width of Z^0 to heavy flavors receives a power correction from a novel QCD mechanism, which is not suppressed by inverse powers of M_Z,…

Anomalous 3-jet and Heavy Quark Fragmentation
Yu Jia
Heavy hadron production in annihilation is studied in the framework of heavy-quark recombination mechanism. This mechanism predicts a new type of 3-jet event such as $b\ba…
