Heat kernel approach to the one-loop effective action for nonlinear electrodynamics
Evgeny I. Buchbinder, Darren T. Grasso, Joshua R. Pinelli
We develop a heat kernel method to compute the one-loop effective action for a general class of nonlinear electrodynamic (NLED) theories in four dimensional Minkowski spacetime. Wo…
Heterotic Flux Vacua with a Small Superpotential
Evgeny I. Buchbinder, Andrei Constantin, Lucas T. Y. Leung +2
We study heterotic Calabi--Yau compactifications with NSNS three-form flux in view of moduli stabilisation and investigate whether the value of the flux superpotential eval…
Gauge-invariant off-shell formulations for 3D massive higher-spin supermultiplets
Evgeny I. Buchbinder, Arcadia J. Fegebank, Sergei M. Kuzenko
Making use of the known off-shell formulations for massless higher-spin supermultiplets in four dimensions, gauge-invariant off-shell actions for massive higher-spin $…
Massless higher-spin supermultiplets in 5D harmonic superspace
Evgeny I. Buchbinder, Sergei M. Kuzenko, Igor B. Samsonov
Off-shell actions for massless higher-spin supermultiplets in five dimensions (5D) are constructed in harmonic superspace in terms of unconstrained prepotentials. C…
Three-point functions of higher-spin supercurrents in 4D SCFT: general formalism for arbitrary superspins
Evgeny I. Buchbinder, Jessica Hutomo, Benjamin J. Stone
We analyse the general structure of the three-point functions involving conserved higher-spin ``vector-like" supercurrents in four-dimensional…
