[A1n_d2n] [External] [EXTERNAL] APS April Meeting-g2n abstract

[Arun Tadepalli]

Hello Melanie,

Abstract looks good! Some minor comments:

Line 4: faction —> fraction

Perhaps add one sentence at the end (if you have not exceeded the word limit) that the current status of the data analysis will be reported in this talk (or something along those lines).

Cheers,

Arun

Hi Melanie,

The abstract reads well, however I suggest to slightly modify the beginning and the end of the last sentence of your abstract.

Due to the non-perturbative nature of QCD, making absolute predictions of nucleon spin structure is generally difficult, and there remains little known about the contribution of quark orbital angular momentum (OAM) to the total nucleon spin.    ——>

Due to the non-perturbative nature of QCD, making absolute predictions of nucleon spin structure is generally difficult. While successful lattice QCD calculations of spin and orbital angular momentum (OAM) of the quarks and gluons, integrated over their longitudinal momentum faction (xBj), exist, there remains much to learn about their xBj-dependence. With the breakthrough of the quasi-pdfs formalism, confronting ab-initio calculations of unintegrated spin observables including OAM will be possible.

End of last sentence:
The wide Q2 range will explore possible Q2 dependence on An1 , provide the first precision data in the valence quark region above x = 0.61, and therefore test various predictions from the relativistic constituent quark model and perturbative QCD. ——>

I hope this helps.

Hi Everyone,

I've attached my abstract as well for the APS submission. Please let me know any of your comments.

Thank you,

Hello everyone,

I have attached the first draft of the g2n abstract for APS April meeting. It would be really helpful if you could provide your comments.

Thank you.
