Investigation of their polarization properties over certain kinematical regions may show that gluon distributions are governed by the Balitsky-Fadin- Kuraev-Lipatov equations.
Investigation of their polarization properties over certain kinematical regions may show that gluon distributions are governed by the Balitsky-Fadin- Kuraev-Lipatov equations. Their elastic and inelastic production is studied at the HERA collider, (*) and the pattern formed on the spark chamber trace when they decay into a positron and an electron may help explain their name. Discovered independently by Samuel Ting and Burton Richter in 1974, they have a surprisingly long lifetime of 10-20 seconds. FTP, name these neutral particles with a rest mass about 7200 times that of the electron, which consists of a charm and anti-charm quark.
