Testing M(atrix) Theory at Two Loops
This lecture is based on two papers; a first paper that was written with Melanie Becker [1] and a second paper that we wrote with our collaborators Joe Polchinski and Arkady Tseytlin [2]. M-theory is our most promising candidate of being a quantum theory in eleven dimensions that includes gravity. Although we do not have a complete answer to the question what M-theory is we understand several a...
متن کاملNoncommutative Φ 4 Theory at Two Loops
We study perturbative aspects of noncommutative field theories. This work is arranged in two parts. First, we review noncommutative field theories in general and discuss both canonical and path integral quantization methods. In the second part, we consider the particular example of noncommutative Φ 4 theory in four dimensions and work out the corresponding effective action and discuss renormali...

متن کاملNegative Dimensional Integration: ”lab Testing” at Two Loops
Negative dimensional integration method (NDIM) is a technique to deal with D-dimensional Feynman loop integrals. Since most of the physical quantities in perturbative Quantum Field Theory (pQFT) require the ability of solving them, the quicker and easier the method to evaluate them the better. The NDIM is a novel and promising technique, ipso facto requiring that we put it to test in different ...
متن کاملComplete solution for M(atrix) theory at two loops
The complete result for the effective potential for two graviton exchange at two loops in M(atrix) theory can be expressed in terms of a generalized hypergeometric function.
