Research
Current Areas of Study
We are a small theoretical physics group based in Khon Kaen University, Thailand. Keep reading to find out what we are currently investigating.
Beyond Standard Model of Particle Physics
We are mainly interested in beyond standard model of particle physics. The ongoing projects are model building aspects of dark matter, dark radiation, dark energy, axion. The interplay between collider physics and astrophysics is another focus.
Cosmology
The theoretical topics of cosmology is the main research interest. The current topics are alternative theories of gravity, cosmological phase transition and inflationary universe with beyond standard models.
Hadron Physics
We mainly work on the exotic hadronic spectroscopy, meson-photoproductions and violations of the fundamental symmetries in a few body systems of the nucleon by using chiral effective field theory, chiral quark model and large-Nc QCD operator analysis approaches.

A Kaluza-Klein Inspired Brans-Dicke Gravity with Dark Matter and Dark Energy Model
We propose the Kaluza-Klein inspired Brans-Dicke gravity model containing possible existence of dark matter and dark energy. The massive scalar field coupled with gravity in 5 dimensional spacetime can be reduced to 4 dimensional gravity along with the dilaton, gauge fields, and the tower of scalar fields. We then use the dynamical system approach to analyze the critical points and their corresponding physical parameters. We found that in the case where only the zero mode of the Kaluza-Klein scalar is decoupled, the system contains both dark matter and dark energy phase depending on the mass parameter with the presence of the gauge field.
