Constraints on Higher Derivative Operators in the Matrix Theory Effective Lagrangian
The consistency of Matrix theory with supergravity requires that in the large Nc limit terms of order v in the SU(Nc) Matrix effective potential are not renormalized beyond one loop in perturbation theory. For SU(2) gauge group, the required non-renormalization theorem was proven recently by Paban, Sethi and Stern. In this paper we consider the constraints supersymmetry imposes on these terms f...
متن کاملConstraints on Higher Derivative Operators in Maximally Supersymmetric Gauge Theory
Following the work of Dine and Seiberg for SU(2), we study the leading irrelevant operators on the moduli space of N = 4 supersymmetric SU(N) gauge theory. These operators are argued to be one-loop exact, and are explicitly computed.
متن کاملRenormalization of Higher Derivative Operators in the Matrix Model
M -theory is believed to be described in various dimensions by large N field theories. It has been further conjectured that at finite N , these theories describe the discrete light cone quantization (DLCQ) of M theory. Even at low energies, this is not necessarily the same thing as the DLCQ of supergravity. It is believed that this is only the case for quantities which are protected by non-reno...
متن کاملComments on Higher Derivative Operators in Some SUSY Field Theories
We study the leading irrelevant operators along the flat directions of certain supersymmetric theories. In particular, we focus on finite N = 2 (including N = 4) supersymmetric field theories in four dimensions and show that these operators are completely determined by the symmetries of the problem. This shows that they are generated only at one loop and are not renormalized beyond this order. ...
متن کاملHigher Order Derivative Constraints in Qualitative Simulation
Qualitative simulation is a useful method for predicting the possible qualitatively distinct behaviors of an incompletely known mechanism described by a system of qualitative diierential equations (QDEs). Under some circumstances, sparse information about the derivatives of variables can lead to intractable branching (or \chatter") representing uninteresting or even spurious distinctions among ...
