We discuss $\gamma^* \gamma^* \to \eta_c(1S)\, , \,\eta_c(2S)$ transition form factor
for both virtual photons. The general formula is given.
We use different models for the $c \bar c$ wave function
obtained from the solution of the Schr\"odinger equation for
different $c \bar c$ potentials: harmonic oscillator, Cornell,
logarithmic, power-law, Coulomb and Buchm\"uller-Tye.
We compare our...
Quantifying the differences between nuclear and hadronic collisions, phenomenological known as medium modification due to multiple scatterings between the hard probe and medium, can provide a solid baseline for unambiguous identification of the fundamental medium property. In this talk, we consider parton propagation in cold nuclear matter within the framework of high twist expansion, which...
Parton distribution functions (PDFs) are mandatory inputs in high energy scattering and also play an important role in searching for new physics at high energy. The recently proposed large momentum effective theory allows one to access the PDFs from first principle Lattice QCD. In this talk, I will discuss the recent progresses on quasi-PDFs, in particular on the gluon quasi-PDFs.

Sign problem is an obstacle in lattice studies of supersymmetric gauge theories including a numerical verification of AdS/CFT. Tensor network is an attractive approach to overcome this problem. We present a numerical result of the tensor network approach in two-dimensional complex phi^4 theory with finite chemical potential.
For long time, gravity is used for learning dynamical aspects of QCD, because holography connects gravity and QFT. In this talk, I will review the opposite direction: learning about gravity from QFT. In particular, I will focus on the quantum nature of black hole. Techniques developed among QCD-practitioners turned out to be useful for quantum gravity. At the same time, quantum...
