More than expected

CDF observes approximately 740 events in the muon decay mode. CDF looked for a signature of three muons, the mass of two oppositely charged muons being consistent with that of the J/ψ particle.

Never alone

Scientists have tuned models to describe the average properties of the mesons created in the fragmentation process, CDF watched what happens to the end of the string that remains immediately after the part connected to the heavy quark is broken.

This plot shows CDF data at 1.96, 0.9 and 0.3 TeV on the charged-particle density in the transMIN region as defined by the leading charged particle as a function of the transverse momentum of the leading charge particle, PTmax. Almost all scientific publications on research at the Tevatron or the LHC focus on the physics of what happens when a postcollision particle, in particular a quark or gluon, shoots well away from the path of the incoming colliding beams. However,…

Scientists on the CDF and DZero experiments at the U.S. Department of Energy’s Fermi National Accelerator Laboratory have announced that they have found the final predicted way of creating a top quark, completing a picture of this particle nearly 20 years in the making.
