Grant: Subatomic Physics Envelope - Individual

Who would not want to know the basic constituents of our world and the way they interact? Nuclear and particle physics studies exactly that. According to the Standard Model of particle physics, there are six types of quarks, six types of leptons, and corresponding anti-particles connected by four fundamental interactions. However, the recent evidence coming from neutrino oscillation, dark matter and dark energy, and quantum gravity showed that the 40-year old Standard Model may be incomplete, and that we may be at the threshold of a new theory and ""New Physics"". One way to look for possible signals of new physics is with high-precision experiments at lower energy which can provide indirect access to physics at multi-TeV scales and play an important complementary role to the Large Hadron Collider research program. This research requires both experimental and theoretical effort, and the new-generation experiments will need a new degree of precision from theory. My colleagues and I strive to bring subatomic physics computations to the next level and to provide the most precise and reliable theoretical input for the high-precision experiments by taking advantage of the new semi-automated symbolic computing methods. Our innovative computational models can be used for a wide range of applications, including next-to-leading and next-to-next-to-leading electroweak radiative corrections for M?ller scattering, electron-proton and positron-proton scattering, modeling pion electroproduction, evaluating electric and magnetic dynamical polarizabilities for hadrons, and many others. This research program can be a crucial contribution to cutting-edge Canadian science in the coming decade, and it would also allow for training a new generation of researchers who would enable Canada to maintain its position at the forefront of world-class research for years to come.
