Duality and the signature of space-time

CM Hull - Journal of High Energy Physics, 1999 - iopscience.iop.org
Versions of M-theory are found in spacetime signatures (9, 2) and (6, 5), in addition to the
usual M-theory in 10+ 1 dimensions, and these give rise to type IIA string theories in 10 …

Self-dual supersymmetry and supergravity in Atiyah-Ward space-time

SV Ketov, H Nishino, SJ Gates Jr - Nuclear Physics B, 1993 - Elsevier
We study supersymmetry and self-duality in a four-dimensional space-time with the
signature (2, 2), that we call the Atiyah-Ward space-time. Dirac matrices and spinors, in …

Why auxiliary fields matter: the strange case of the 4D, N= 1 supersymmetric QCD effective action (II)

SJ Gates Jr - Nuclear Physics B, 1997 - Elsevier
Within a four-dimensional N= 1 superspace, we present a new ansatz for the Skyrme term
and for the gauged WZNW term embedded into a superaction. We use the new chiral-non …

Einstein supergravity and new twistor string theories

M Abou-Zeid, CM Hull, LJ Mason - Communications in mathematical …, 2008 - Springer
A family of new twistor string theories is constructed and shown to be free from world-sheet
anomalies. The spectra in space-time are calculated and shown to give Einstein …

Self-dual supergravity and twistor theory

M Wolf - Classical and Quantum Gravity, 2007 - iopscience.iop.org
By generalizing and extending some of the earlier results derived by Manin and Merkulov, a
twistor description is given of four-dimensional-extended (gauged) self-dual supergravity …

[HTML][HTML] Sen's mechanism for self-dual super Maxwell theory

G Barbagallo, PA Grassi - Nuclear Physics B, 2024 - Elsevier
In several elementary particle scenarios, self-dual fields emerge as fundamental degrees of
freedom. Some examples are the D= 2 chiral boson, D= 10 Type IIB supergravity, and D= 6 …

Static vacuum solutions on curved space–times with torsion

H Shabani, AH Ziaie - International Journal of Modern Physics A, 2018 - World Scientific
The Einstein–Cartan–Kibble–Sciama (ECKS) theory of gravity naturally extends Einstein's
general relativity (GR) to include intrinsic angular momentum (spin) of matter. The main …

Super multi-instantons in conformal chiral superspace

W Siegel - Physical Review D, 1995 - APS
We reformulate self-dual supersymmetric theories directly in conformal chiral superspace,
where superconformal invariance is manifest. The superspace can be interpreted as the …

Self-dual supergravity theories in 2+ 2 dimensions

E Bergshoeff, E Sezgin - Physics Letters B, 1992 - Elsevier
Starting from the new minimal multiplet of supergravity in 2+ 2 dimensions, we construct two
types of self-dual supergravity theories. One of them involves a self-duality condition on the …

N= 1 super-Chern-Simons coupled to parity-preserving matter from Atiyah-Ward space-time

MA De Andrade, OM Del Cima, LP Colatto - Physics Letters B, 1996 - Elsevier
In this letter, we present the Parkes-Siegel formulation for the massive Abelian N= 1 super-
QED2+ 2 coupled to a self-dual supermultiplet, by introducing a chiral multiplier superfield …
