"New Physics can appear at any moment but it is now conceivable that no new physics will show up at the LHC" Guido Altarelli, LHC Nobel Symposium, May 15th 2013 It is funny reading the above quote if…

Hofstadter's Butterfly, a complex pattern of the energy states of electrons that resembles a butterfly, has appeared in physics textbooks as a theoretical concept of quantum mechanics for nearly 40…

Finally the decay of Higgs bosons to b-quark pairs is emerging from LHC data, too. That decay mode is the highest-probability one - about four out of five Higgs bosons will prefer to yield b-quarks…

Supersymmetry, the extension of the Standard Model of particle physics that was once sold as an almost certain discovery that the LHC experiments would bump into upon starting to collect proton-…

In 1992 the top quark had not been discovered yet, and it did not make much sense for the CDF collaboration to have a full meeting devoted solely to it; rather, analyses targeting the search of the…

While school-age models of atomic nuclei show them as being spherical, like a basketball, they are more like the shape of a football.  Yet for some particular combinations of protons and…

With the Higgs boson in the bag, the game called "global fit" that particle physicists have been playing for a couple of decades has changed significantly. The knowledge of the Higgs boson mass…

"A detailed study of four-jet hadronic events at LEP 1.5 has been reported by the ALEPH collaboration. From selected four-jet events, the invariant masses of jet pairs are computed, and out of the…

ATLAS has just produced a very nice new study of jet production in Z-boson events. I will describe a sample graph below, but before I do I find it useful to explain to the less knowledgeable among…

One of the most intriguing effects in subatomic physics is the phenomenon of violation of the discrete symmetry called "CP". It is intriguing at various levels. First of all, CP violation is…
