The word “decay,” in the world of physics, has a slightly different meaning than what you might think. What is subatomic decay? by Don Lincoln.
Quarks and gluons are more generically called “partons.” http://news.fnal.gov/2012/05/quarks-and-gluons-and-partons-oh-my/, by Don Lincoln.
Measuring the “Pole Mass” of the top quark at the Tevatron (CDF) http://news.fnal.gov/2016/06/poles-and-masses/, by Leo Bellantoni.
Looking for exceptionally heavy particles decay into two Higgs bosons, which would preferentially decay into four B quarks. http://news.fnal.gov/2016/03/busy-bees/, by Don Lincoln.
Any sign of new particles at the much higher energy of LHC Run 2? http://news.fnal.gov/2016/02/looking-for-signs-dijet-resonances/, by Bo Jayatilaka
A new observation of the 4-quark bound state. http://news.fnal.gov/2016/02/dzero-discovers-a-new-particle-consistent-with-a-tetraquark/, by Dmitri Denisov and Paul Grannis: the co-spokespersons for the DZero experiment.
It is possible to create both a J/ψ (“Jay Sigh”) and an Υ (“OOPS-i-lon”) simultaneously. What we learn from these events has a lot to do with the way quarks are stuck together inside the proton. http://www.fnal.gov/pub/today/archive/archive_2015/today15-11-12.html, by Leo Bellantoni.
Is there a fourth generation of quarks? CMS says, “Not yet.” http://www.fnal.gov/pub/today/archive/archive_2015/today15-10-09.html, by Don Lincoln.
Are there other forces? CMS sets new limits. http://www.fnal.gov/pub/today/archive/archive_2015/today15-06-19.html, by Jim Pivarski
CMS seems to see a decay mode of the Higgs boson that indicates the Higgs can mix leptons of different flavors. http://www.fnal.gov/pub/today/archive/archive_2015/today15-03-27.html, by Jim Pivarski.
