Light S-wave pentaquarks on the light front
Fangcheng He, Edward Shuryak, Wan Wu +1
We construct an explicit basis set for pentaquark states on a regular 4-simplex, that diagonalizes the Hamiltonian for light pentaquarks with confinement on the light front (LF). T…
Threshold photo-production of off light nuclei
Fangcheng He, Ismail Zahed
We analyze threshold photoproduction of heavy mesons off a deuteron and Helium-4, using the QCD factorization method. Assuming large skewness, the production amplitude is dominated…
Helium-4 gravitational form factors: exchange currents
Fangcheng He, Ismail Zahed
We evaluate the leading exchange corrections to the Helium-4 gravitational form factors (GFFs) upto momenta of the order of the nucleon mass. We use both the K-harmonic method with…
Deuteron gravitational form factors: exchange currents
Fangcheng He, Ismail Zahed
Following on our recent analysis of the energy momentum tensor (EMT) of light nuclei in the impulse approximation, we evaluate the leading exchange corrections also upto momenta of…
Trace anomaly form factors from lattice QCD
Bigeng Wang, Fangcheng He, Gen Wang +4
The hadron mass can be obtained through the calculation of the trace of the energy-momentum tensor in the hadron which includes the trace anomaly and sigma terms. The anomaly due t…
Gravitational form factors of light nuclei: Impulse approximation
Fangcheng He, Ismail Zahed
The gravitational form factors of light nuclei are evaluated up to momenta of the order of the nucleon mass, using the impulse approximation. The nucleon gravitational form factors…
