Title: A new regularization of loop integral and a new look on the hierarchy problem

Speaker: Dr. WANG Wenyu

Time: 3:00PM, Mar. 25th (Wednesday)

Place: Theoretical Physics Division，319

Abstract:

In this talk we show a new regularization scheme which is motivated by the Bose-Einstein condensation. The energy of the virtual particle is considered as discrete. Summing them and regulating the summation by the Riemann $\zeta$ function can give the result of loop integral.All the divergences vanish, we can get almost the same results as Dimensional Regularization.The prediction beyond Dimensional Regularization is also shown in the QED. The hierarchy problem of the radiative correction of scalar mass completely vanish.
