How To Produce Exotic Baryons
On the right is shown the calculated cross section as a function of the incident photon energy: it of course is a "breit-wigner" (or Lorenzian) shape, characteristic of the resonant production. The Gamma parameter is the width assumed for the state.
A Four-Sigma Evidence Of New Physics In Rare B Decays Found By LHCb, And Its
Today I received news of an interesting measurement of angular distributions of the decay products in the rare decay of the B meson to a K* and a muon pair - one of the specialties of the LHCb collaboration, which has more horse-power in some of these ...

An Exquisite New W Mass Measurement From CDF !
Because of the missing longitudinal information, the "transverse mass" has a shape different from that of a resonance: it is not a Breit-Wigner, but rather a "Jacobian peak", sharp on the right edge, and more blunt on the other.
Notes On Higgs Branching Fractions
In my latest instantiation of the "Guess the plot" series I offered a clipped part of a graph showing branching fractions of the Higgs boson.
