High energy neutrino interactions induce charmed hadron production at the level of a few percent and therefore they constitute a powerful tool to study charm physics. The CHORUS experiment can profit of the extremely high spatial resolution of nuclear emulsions to identify and study the charm production and decay vertexes. This experiment is now analyzing the final data sample and publishing ne...

Projected parameters of the EIC are well-suited for testing for the existence of the nonperturbative intrinsic mechanism for charm quark production. We present estimates for semi-inclusive DIS charm production for various EIC con gurations and examine the e ects of intrinsic charm contributions.

A pedagogically oriented review is given of progress made over the past year in our understanding of physics related to the charm quark. Included are discussions of the Rc deficit, the ψ ′ anomaly, charm spectroscopy, D nonleptonic decays, searches for flavor-changing neutral currents, new limits on D 0 − ¯ D 0 mixing and prospects for future experimental studies of the charm sector.

Heavy quark production in hadronic reactions is reasonably well described by perturbative QCD. However, in heavy ion collisions, final-state interactions may affect the spectra of produced heavy mesons. At the Relativistic Heavy Ion Collider (RHIC), a dense partonic system, often called the quark gluon plasma (QGP), is expected to be formed at the early stage. Since the QGP may induce a strong ...

This p&per outlines the pqtential for new particle searches in tau and charm physics at a Tau-Charm Factory.

Using a D meson cloud model we calculate the squared charm radius of the nucleon . The ratio between this squared radius and the ordinary baryon squared radius is identified with the probability of “seeing” the intrinsic charm component of the nucleon. Our estimate is compatible with those used to successfully describe the charm production phenomenology. In the early eighties there was a hope t...

We propose a sensitive measurement of the charm total cross section at RHIC through muon identification from charm semileptonic decay at low transverse momentum (pT ). This can test the binary-collision scaling (Nbin) properties of the charm total cross section and be used to study if heavy-flavor quarks as a probe are produced exclusively at the initial impact. The effects of the form factor o...

We investigate the charm sector of the nucleon structure phenomenologically, using the most up-to-date global QCD analysis. Going beyond the common assumption of purely radiatively generated charm, we explore possible degrees of freedom in the parton parameter space associated with nonperturbative (intrinsic) charm in the nucleon. Specifically, we explore the limits that can be placed on the in...

We present a study on the spectra for heavy flavor (charm and bottom) decayed electrons in 200 GeV p+p collisions and provide the relative contributions of charm and bottom hadrons from the PYTHIA calculations. The results suggest that the crossing point of the electron spectra from charm and bottom decays is above 7 GeV/c and bottom contribution is not dominant for electron pT < 3 GeV/c. The u...
