Heavy Flavor Production
Recent experimental results on phow and hadmpmduction of heavy flavor particles are reviewed. After a short introduction on the recent advances in the theoretical ideas describing the production of heavy flavors, current experimental techniques used in heavy flavor search in fixed target experiments an? briefly discussed. New results on the production characteristics, production ctoss section a...
متن کاملHeavy Flavor Weak Decays
Weak decays of heavy flavor hadrons play a special role in our understanding of physics of the Standard Model and beyond. The measured quantities, however, result from a complicated interplay of weak and strong interactions. Weak leptonic and semileptonic decays are reasonably well understood, whereas weak hadronic decays present challenges to theory. In this talk, we review the present status ...
متن کاملHeavy Flavor Theory : Overview ⋆
An introduction to the heavy quark effective theory and its symmetries is given. Some implications of the heavy quark spin and flavor symmetries are discussed. Recent results on fragmentation to quarkonium states are reviewed. ⋆ Work supported in part by the U.S. Dept. of Energy under Grant no. DE-FG03-92-ER 40701.
متن کامل) Heavy Flavor Contributions
In deep-inelastic processes the heavy flavor Wilson coefficients factorize for Q2 ≫ m2 into the light flavor Wilson coefficients of the corresponding process and the massive operator matrix elements (OMEs). We calculate the O(αs) and O(α 3 s) massive OME for the flavor non-singlet transversity distribution. At O(αs) the OME is obtained for general values of the Mellin variable N , while at O(αs...
متن کاملOn the role of heavy flavor parton distributions at high energy colliders
We compare ‘fixed flavor number scheme’ (FFNS) and ‘variable flavor number scheme’ (VFNS) parton model predictions at high energy colliders. Based on our recent LO– and NLO–FFNS dynamical parton distributions, we generate radiatively two sets of VFNS parton distributions where also the heavy quark flavors h = c, b, t are considered as massless partons within the nucleon. By studying the role of...
