New way to access the quark fragmentation functions in electron-positron annihilation
Aram Kotzinian, Hrayr H. Matevosyan, Anthony W. Thomas
The description of the polarized quark hadronization process is one of the most challenging problems in the physics of strong interactions. The various single hadron and dihadron f…
Semi-inclusive back-to-back production of a hadron pair and a single hadron in annihilation
Hrayr H. Matevosyan, Aram Kotzinian, Anthony W. Thomas
Inclusive hadron production in annihilation has long been used to study both single hadron fragmentation functions (FF) and dihadron fragmentation functions (DiFF). In par…
Accessing quark helicity in and SIDIS via dihadron correlations
Hrayr H. Matevosyan
The correlation between the longitudinal polarization of a fragmenting quark and the transverse momenta of the produced hadrons was predicted over two decades ago. Nevertheless, ex…
Polarized EMC Effect in the QMC Model
Stephen Tronchin, Hrayr H. Matevosyan, Anthony W. Thomas
The ratios of the in-medium to free nucleon structure functions for the unpolarized and polarized cases are obtained using the MIT bag model for the free case, along with the QMC m…
Semi-inclusive production of two back-to-back hadron pairs in annihilation revisited
Hrayr H. Matevosyan, Alessandro Bacchetta, Daniël Boer +4
The cross section for back-to-back hadron pair production in annihilation provides access to the dihadron fragmentation functions (DiFF) needed to extract nucleon parton d…
Accessing Quark Helicity through Dihadron Studies
Hrayr H. Matevosyan, Aram Kotzinian, Anthony W. Thomas
We present a new proposal to study the helicity-dependent dihadron fragmentation functions (DiFF), which describe the correlations of the longitudinal polarization of a fragmenting…
