Description
We present a preliminary calculation of the quark energy momentum tensor form factors $T_1(Q^2)$ and $T_1(Q^2)+T_2(Q^2)$ at physical pion mass with valence overlap fermions on 2+1 flavor domain-wall $24^3\times 64$ configurations with $a=0.194\ {\rm{fm}},m_{\pi}=137\ {\rm{MeV}}$ generated by RBC/UKQCD collaboration. With z-expansion fits of the sum of connected and disconneted contributions, we extract the unrenormalized quark momentum and angular momentum fractions.
