First study of twist-3 PDFs for the proton from lattice QCD
Shohini Bhattacharya, Krzysztof Cichy, Martha Constantinou +3
In these proceedings, we summarize the main results from the first-ever calculations of the chiral-even and chiral-odd twist-3 parton distributions, and , of the p…
Twist-3 partonic distributions from lattice QCD
Shohini Bhattacharya, Krzysztof Cichy, Martha Constantinou +3
Twist-3 partonic distributions contain important information that characterizes nucleon's structure. In this work, we show our lattice exploration of the twist-3 PDFs , and…
The role of zero-mode contributions in the matching for the twist-3 PDFs and
Shohini Bhattacharya, Krzysztof Cichy, Martha Constantinou +3
The perturbative procedure of matching was proposed to connect parton quasi-distributions that are calculable in lattice QCD to the corresponding light-cone distributions which ent…
New insights on proton structure from lattice QCD: the twist-3 parton distribution function
Shohini Bhattacharya, Krzysztof Cichy, Martha Constantinou +3
In this work, we present the first-ever calculation of the isovector flavor combination of the twist-3 parton distribution function for the proton from lattice QCD. We use…
Exploring twist-2 GPDs through quasi-distributions in a diquark spectator model
Shohini Bhattacharya, Christopher Cocuzza, Andreas Metz
Quasi parton distributions (quasi-PDFs) are currently under intense investigation. Quasi-PDFs are defined through spatial correlation functions and are thus accessible in lattice Q…
Generalized quasi parton distributions in a diquark spectator model
Shohini Bhattacharya, Christopher Cocuzza, Andreas Metz
Recently the concept of quasi parton distributions (quasi-PDFs) for hadrons has been proposed. Quasi-PDFs are defined through spatial correlation functions and as such can be compu…
