Generalizing Tanisaki's ideal via ideals of truncated symmetric functions
Aba Mbirika, Julianna Tymoczko
We define a family of ideals in the polynomial ring that are parametrized by Hessenberg functions (equivalently Dyck paths or ample partitions).…
Trumpet slices of the Schwarzschild-Tangherlini spacetime
Kenneth A. Dennison, John P. Wendell, Thomas W. Baumgarte +1
We study families of time-independent maximal and 1+log foliations of the Schwarzschild-Tangherlini spacetime, the spherically-symmetric vacuum black hole solution in D spacetime d…
More loops and legs in Higgs-regulated N=4 SYM amplitudes
Johannes M. Henn, Stephen G. Naculich, Howard J. Schnitzer +1
We extend the analysis of Higgs-regulated planar amplitudes of N=4 supersymmetric Yang-Mills theory to four loops for the four-gluon amplitude and to two loops for the five-gluon a…
Higgs-regularized three-loop four-gluon amplitude in N=4 SYM: exponentiation and Regge limits
Johannes M. Henn, Stephen G. Naculich, Howard J. Schnitzer +1
We compute the three-loop contribution to the N=4 supersymmetric Yang-Mills planar four-gluon amplitude using the recently-proposed Higgs IR regulator of Alday, Henn, Plefka, and S…
