Connected-Sea Partons

Keh-Fei Liu, Wen-Chen Chang, Hai-Yang Cheng +1

According to the path-integral formalism of the hadronic tensor, the nucleon sea contains two distinct components called connected sea (CS) and disconnected sea (DS). We discuss ho…

Quark and Glue Momenta and Angular Momenta in the Proton --- a Lattice Calculation

K. F. Liu, M. Deka, T. Doi +10

We report a complete calculation of the quark and glue momenta and angular momenta in the proton. These include the quark contributions from both the connected and disconnected ins…

Is $1^{-} +$ Meson a Hybrid?

Yi-Bo Yang, Ying Chen, Gang Li +1

We calculate the vacuum to meson matrix elements of the dimension-4 operator $\barψγ_4\nblr_i ψ$ and dimension-5 operator $\barψ\epsγ_jψB_k$ of the $1^{-+}$ meson on the lattice an…
