3D Animations for Exploring Nucleon Structure Waverly Gorman HUGS 2016

Outline The Problem The Solution Quark Orbital Angular Momentum Transverse Single-Spin Asymmetry Conclusion

Problem Challenging to pretend that a water bottle represents a nucleon, or a quark, or a gluon Representing 3D processes with compilations of 2D images

Solution 3D computer animations using Blender (free and open source!) https://www.blender.org/ Awarded the Jefferson Science Associates Minority/Female Undergraduate Research Assistantship https://www.jlab.org/news/stories/nmsu-undergrad-receives-jsa- research-assistantship

Quark Orbital Angular Momentum Spin of the nucleon Ji decomposition Jaffe-Manohar decomposition

Quark Orbital Angular Momentum Spin of the nucleon Ji decomposition Jaffe-Manohar decomposition

Quark Orbital Angular Momentum Example: Torque in magnetic dipole field

Transverse Single-Spin Asymmetry (See lectures by M. Diehl)

Transverse Single-Spin Asymmetry

Conclusion Created 3D animations, using Blender, of mechanisms for determining nucleon structure Quark OAM Transverse SSA 3D animations are complicated, but worthwhile in the end 2 semesters of work produced 2 movies (but now I am faster)
