The ulimate goal of theroretical particle physics research is to discover the fundamental structure of matter. Developments of the theory will depend not only on the self consistency of the theory itself but also hints and directions from experimental data from experiments in accelerators like, LHC, RHIC... , and particle astrophysics and cosmology.

In the following, we enlist our research topics in two major categories according to the nature of their corresponding experimental data.

I. Particle Phenomenology

(1) Higher-order calculations in kT factorization
(2) Jet substructure in colliders
(3) Resolving B-CP puzzles in QCD Factorization
(4) Scalar and pseudoscalar glueballs
(5) Radiative decays of B mesons
(6) Scalar mesons in D decays
(7)Quantum gravity
(8) Nonperturbative bound on high multiplicity cross sections in theory in three dimensions from lattice simulation
(9)Neutrino mass and neutrino oscillation
(10)Quantum bit commitment
(11)Quantum teleportation
(12)Application of Statistical Physics Methods to Social and Economic Systems

II. Particle Astrophysics and Cosmology

(1) Decaying superheavy dark matter and subgalactic structure of the Universe
(2) Bound on the time variation of the fine structure constant driven by quintessence
(3) Observational strategies of CMB temperature and polarization experiments
(4) Density perturbation in inflationary universe
(5) Correlated hybrid fluctuations from inflation with thermal dissipation
(6) Off-equilibrium dynamics of the primordial perturbations in the inflationary universe
