elementary particle theory (phenomenology)Overview of the research
My research efforts are devoted to understand physics beyond the standard model of elementary particles, the fundamental description of microscopic/high energy phenomena of nature. The hints may be exhibited in our Universe and introduced by future experiments on earth or in the underground.
