Precise Determinations of the Charm Quark Mass

In this contribution two recent analyses for the extraction of the charm quark mass are discussed. Although they rely on completely different experimental and theoretical input the two methods provide the same final results for the charm quark mass and have an uncertainty of about 1%.

Light Quark Mass Effects in Bottom Quark Mass Determinations

Recent results for charm quark mass effects in perturbative bottom quark mass determinations from Υ mesons are reviewed. The connection between the behavior of light quark mass corrections and the infrared sensitivity of some bottom quark mass definitions is examined in some detail.

Bottom Quark Mass from Υ Mesons: Charm Mass Effects

The effects of the finite charm quark mass on bottom quark mass determinations from Υ sum rules are examined in detail. The charm quark mass effects are calculated at next-to-next-toleading order in the non-relativistic power counting for the Υ sum rules and at order αs for the determination of the bottom MS mass. For the bottom 1S mass, which is extracted from the Υ sum rules directly, we obta...

Charm and Bottom Semileptonic Decays

We review the present status of theoretical attempts to calculate the semileptonic charm and bottom decays and then present a calculation of these decays in the light– front frame at the kinematic point q = 0. This allows us to evaluate the form factors at the same value of q, even though the allowed kinematic ranges for charm and bottom decays are very different. Also, at this kinematic point ...

Charm and bottom heavy baryon mass spectrum from lattice QCD with 2+1 flavors

We present results for the mass spectrum of charm and bottom heavy baryons, using MILC coarse lattice configurations with 2+1 flavors. Clover heavy quark propagators with the Fermilab interpretation and improved staggered light quark propagators are used to construct two point functions with local operators for different flavor and spin states.
