Nonleptonic decays of charm mesons
Amplitude analyses of the $D\sp{+}$, $D\sbsp{s}{+}\ \to\ K\sp{+}K\sp{-}\pi\sp{+}$ and $D\sp{+}$, $D\sbsp{s}{+}\ \to\ \pi\sp{+}\pi\sp{+}\pi\sp{-}$ Dalitz plots are presented using data collected by the Fermilab high energy photoproduction experiment E687. Our data are fit to a model consisting of a …

Production of charm mesons by high energy neutrons
"The charmed mesons D""'±, DO, and D; have been observed in neutron-nucleus collisions at the FNAL Tevatron. A sample of 134 ± 19 events was investigated in the decay D""'±-+ D°1r± with the subsequent decay mode D°-+ K+ K-. The cross section per nucleon for D""'±, at most probable energy ...;s = 35 …

Spectroscopy of exotic charm mesons from lattice QCD
Exotic mesons are mesons that cannot be described as a quark-antiquark pair. The number of exotic mesons has been growing every year in the charm sector and the theoretical understanding of them is often conflicted amongst the community. Some possible explanations include hybrid mesons where the …

Open and Hidden Charm Mesons at Finite Temperature from Anisotropic Lattice QCD
… its large mass and long thermalisation time, the charm quark is an excellent tool with which to probe the plasma. In this thesis I study the dissociation of open and hidden charm mesons. Lattice QCD provides a non-perturbative means of studying the spectral quantities of charmed mesons. The …

Beauty meson to double open charm decays with the LHCb detector
Measurements of beauty meson to double open charm decays are presented. These measurements use data collected in proton-proton collisions by the LHCb detector at the Large Hadron Collider (LHC) between 2011 and 2018. Firstly a search for sixteen rare decays of the $B_c^+$ meson to two charm mesons …

Search for and studies of Quark-Gluon Plasma via dynamics and productions of heavy quarks in proton-proton and heavy ion collisions at the LHC with CMS detector
… The elliptic flow (v2{2}) and v2{4}) for charm mesons using two- and four-particle correlation technique in lead-lead collisions at a nucleon-nucleon center of mass energy 5.02 TeV is presented. The splitting between v2{4}/v2{2} of light charged particles and charm mesons is hinted in …

Doubly charmed B decays with the LHCb experiment
… two studies of $CP$ violation with doubly charmed $B$ decays. Both were performed using Run I data collected by the LHCb experiment in $pp$ collisions at the LHC. This corresponds to 1.0 fb$^{-1}$ collected at a centre-of-mass energy of 7 TeV and 2.0 fb$^{-1}$ collected at a centre-of-mass …
