Puzzling measurement of the Ωc0 charmed baryon lifetime
Today the LHCb collaboration submitted for publication the result of a measurement of the lifetime of the Ωc0 baryon, i.e. a composite particle composed of css quarks. The Ωc0 baryon…
Re-discovery of an exceptionally charming particle
A year ago the LHCb collaboration announced the observation of an exceptionally charmed particle, the Ξcc++ baryon. This particle contains two charm quarks and one up quark, resulting in an…
Long life(time) of the exceptionally charmed particle Ξcc++
Last year the LHCb Collaboration announced the observation of an exceptionally charmed particle, the Ξcc++ baryon. This contains two charm quarks and one up quark, resulting in an overall doubly…
