| Research Abstract |
One loop two and three point functions are expressed in terms of Lauricella FD hypergeometric function in d-dimensional space-time with any combinations of particle masses. Four point functions are expressed by Aomoto-Gelfand Hypergeometric functions. An efficient algorithm has been developed in sector decomposition method for general loop integrations.
