Once more on the BPS bound for the susy kink
Andrei Litvintsev, Peter van Nieuwenhuizen
We consider a new momentum cut-off scheme for sums over zero-point energies, containing an arbitrary function f(k) which interpolates smoothly between the zero-point energies of th…

The Supersymmetric Kink via Higher-Derivative and Momentum Cut-Off Regularization Schemes
Andrei Litvintsev
We study the supersymmetric kink with higher derivative and momentum cut-off regularization schemes. We introduce the new momentum cut-off regularization scheme which we call ``gen…
