Charm physics covers the studies of particles containing a charm-quark. In our group we are interested in the decays of the mesons D+(-) and Ds+(-). The D+ is composed of a charm quark (c) and a down antiquark (d), while the D- is composed of a charm antiquark (c) and a down quark (d). The Ds+ is composed of a charm quark (c) and a strange antiquark (s), while the D- is composed of a charm antiquark (c) and a strange quark (s).
The decays of D+(-) and Ds+(-) into 3 charged hadrons are a good laboratory for the study of hadronic physics and CP violation. In our studies, we use the large samples of charm mesons produced in the proton-proton collisions at the Large Hadron Collider and collected by the LHCb experiment.
The LHCb charm group from Rio is composed of people from LAPE/IF-UFRJ, from CBPF and from PUC-Rio.
