New Dual Conformally Invariant Off-Shell Integrals
Evidence has recently emerged for a hidden symmetry of scattering amplitudes in N = 4 super Yang-Mills theory called dual conformal symmetry. At weak coupling the presence of this symmetry has been observed through five loops, while at strong coupling the symmetry has been shown to have a natural interpretation in terms of a T-dualized AdS5. In this paper we study dual conformally invariant off...
متن کاملDual Band Slotted Patch Antenna for On/Off-body Communication
Body Centric Wireless Communication (BCWC) has been topic of much research in recent years. In this manuscript, a novel low-cost microstrip patch antenna is designed for on-/off-body communication with a dual-band operation. The proposed structure exhibits a monopole-like radiation pattern at 2.45 GHz and a broadside radiation at 4.8 GHz, simultaneously. Lateral dimensions of 42 mm × 46 mm and ...
متن کاملDual Amplitudes and Basic Assumptions
Four simple assumptions for scattering amplitudes are proposed in order to derive dual amplitudes. The assumptions are conventional except the one which states that each term of an amplitude, corresponding to a certain combination of Regge poles ins, t and u channels, is constructed by a triple product form of three unknown functions, U1 (t), {12 (s) and us (u). This is arrived at by an abstrac...

متن کاملThe Self-dual Sector of Qcd Amplitudes
We provide an action for self-dual Yang-Mills theory which is a simple truncation of the usual Yang-Mills action. Only vertices that violate helicity conservation maximally are included. One-loop amplitudes in the self-dual theory then follow as a subset of the Yang-Mills ones. In light-cone gauges this action is almost identical to previously proposed actions, but in this formulation the vanis...
