Abstract:
We present a new and very high statistics study of D and D_s semileptonic decay form factors on the lattice. We work with MILC N_f=2+1 lattices and use the Highly Improved Staggered Action (HISQ) for both the charm and the light valence quarks. We use both scalar and vector currents to determine the form factors f_0(q^2) and f_+(q^2) for a...

Abstract:
We describe precision measurements that shed light on non-perturbative strong interactions involving the charm quark. The natural width of the D*+ meson is measured with a dataset 50 times larger than that of the previous measurement, leading to significant improvement in precision. We also measure the mass, width, and several new...

Abstract:
We study charmed and strange baryon resonances that are generated dynamically within a unitary meson-baryon coupled-channel model which incorporates heavy-quark symmetry [1,2]. This is accomplished by extending the SU(3) Weinberg-Tomozawa chiral Lagrangian to SU(8) spin-flavor symmetry and implementing a strong flavor symmetry breaking. The...

Abstract:
D-Dbar mixing has been well established with the combination of several measurements, but so far there is no single measurement with significance over 5 standard deviations. We report the results of a new measurement of the charm parameters y_{CP} and Delta y. The analysis sensitivity is maximized by using the entire dataset collected...

Abstract:
Recent studies of the interaction of vector mesons with nuclei make possible and opportune the study of the interaction of the $J/\psi$ with nuclei and the investigation of the origin of the $J/\psi$ suppression in its propagation thorough a nuclear medium. We observe that the transition of $J/\psi N$ to $VN$ with $V$ being a light vector,...

Abstract:
We report on several new results involving charmonium and charmonium-like states. This includes tight limits on the production of the charged states Z1(4050)+ and Z2(4250)+ reported by Belle, improved measurement of the X(3915), and studies involving the final states eta_c \pi+\pi- and \psi(2S)\pi+ \pi-.

Abstract:
We present the prospects for studying quantum correlated charm decays at the psi(3770) using 1ab^-1 of data at SuperB. The impact of studying the time-dependence of such double tagged decays upon measurements in other charm environments will be discussed.

Abstract:
The resolution of Dyson-Schwinger equations leads to the freezing of the QCD running coupling (effective charge) in the infrared, which is best understood as a dynamical generation of a gluon mass function, giving rise to a momentum dependence which is free from infrared divergences. We calculate the static interquark potential by...

Abstract:
The BESIII detector, with the BESCII e+e- collider, has collected the world largest data sample, 2.89/fb, taken at sqrt(s)=3.773 GeV which is very close to the nominal mass of the psi(3770) state. As the psi(3770) decays into a pair of DDbar most of the time, a relatively clean and simple event environment is obtained, and thus, it is very...

Abstract:
Flavor changing neutral current decays in the charm sector are very rare within the standard model, and thus provide a unique environment for searching for new physics. We report tight upper limits on branching fractions of a variety of such processes involving charged and neutral charm mesons and baryons, including processes...
