متن کاملFragmentation inside an identified jet
Using Soft-Collinear Effective Theory (SCET) we derive factorization formulae for semi-inclusive processes where a light hadron h fragments from a jet whose invariant mass is measured. Our analysis yields a novel “fragmenting jet function” G h i (s,z) that depends on the jet invariant mass √ s, and on the fraction z of the large light-cone momentum components of the hadron and the parent parton...
متن کاملTHE ROLE OF QUARK POLARIZATION IN HEAVY QUARK FRAGMENTATION
We calculate the exact fragmentation functions for c and b quark fragmentation taking into account the spin orientation of the initial heavy quark in the form of analytical and rather simple expressions. Our calculations show that spin orientation may have an important effect on the fragmentation spectrum. This effect is more striking in the cases of c ?D, D*; c? ? , ? , and ?B , B *.
متن کاملHadron production from quark coalescence and jet fragmentation
Transverse momentum spectra of pions, protons, and antiprotons in Au + Au collisions at intermediate RHIC energy √ sNN = 62 GeV are studied in a model that includes both quark coalescence from the dense partonic matter and fragmentation of the quenched perturbative minijet partons. The resulting baryon to meson ratio at intermediate transverse momenta is predicted to be larger than that seen in...
متن کاملJet Production and Quark Fragmentation Results from Pep
Results on jet production and quark fragmentation are presented from the five detectors at the PEP e+estorage ring at the Stanford Linear Accelerator Center: DELCO (Caltech-SLAC-Stanford), I-IRS (ArgonneIndiana-LBL-Michigan-Purdue-SLAC), MAC (ColoradoFrascati-Houston-Northeastern-SLAC-Stanford-UtahWisconsin), MARK II (SLAC-LBL-Harvard), and TPC (LBL-Johns Hopkins-UCLA-UC Riverside-Yale). All da...
