Description
With the upcoming Electron-Ion Collider, interest in proton tomography has greatly increased due to experiments, like DVCS are able to be conducted. A large set of functions that gives a great amount of information about the structure are Generalized Parton Distribution functions (GPDs). Recently, the $x$-dependence of GPDs has been extracted from lattice QCD. Utilizing a novel method that gives access to a wide range for the kinematic parameters (PRD 106 (2022) 11, 114512), we extract the transversity GPDs for the proton: $H_T$, $E_T$, $\tilde{H}_T$, and $\tilde{E}_T$. Calculations are done in zero-skewness with an $N_f = 2+1+1$ ensemble of twisted mass fermions with a clover improvement. The quark masses give a pion mass of roughly 260 MeV.
