Factorization and unitarity in superstring theory [PDF]
Journal of High Energy Physics, 2005 The overall coefficient of the two-loop 4-particle amplitude in superstring theory is determined by making use of the factorization and unitarity. To accomplish this we computed in detail all the relevant tree and one-loop amplitudes involved and determined their overall coefficients in a consistent way.

``Alternative $N=(4,0)$ Superstring and $\s$-Models''
, 1994 We present an alternative $N=(4,0)$ superstring theory, with field content different from that of previously-known $N=(4,0)$ superstring theories. This theory is presented as a non-linear $\s$-model on the coset $SU(n,1) / SU(n) \otimes U(1)$ as the ...

Open superstring field theory based on the supermoduli space [PDF]
, 2017 A bstractWe present a new approach to formulating open superstring field theory based on the covering of the supermoduli space of super-Riemann surfaces and explicitly construct a gauge-invariant action in the Neveu-Schwarz sector up to quartic ...

Resolving Witten's Superstring Field Theory [PDF]
, 2013 We regulate Witten's open superstring field theory by replacing the picture-changing insertion at the midpoint with a contour integral of picture changing insertions over the half-string overlaps of the cubic vertex.

Conformal Relativity versus Brans–Dicke and Superstring Theories
Entropy, 2012 We show how conformal relativity is related to Brans–Dicke theory and to low-energy-effective superstring theory. Conformal relativity or the Hoyle–Narlikar theory is invariant with respect to conformal transformations of the metric.

On the cigar CFT and Schwarzschild horizons
Nuclear Physics B, 2023 Aspects of shock waves and instantly-created folded strings operators in the supersymmetric SL(2)k/U(1) CFT, and their relevance to the near-horizon physics of Schwarzschild black holes in perturbative superstring theory, are presented.

DIS off glueballs from string theory: the role of the chiral anomaly and the Chern-Simons term
Journal of High Energy Physics, 2018 We calculate the structure function F 3(x, q 2) of the hadronic tensor of deep inelastic scattering (DIS) of charged leptons from glueballs of N=4 $$ \mathcal{N}=4 $$ SYM theory at strong coupling and at small values of the Bjorken parameter in the gauge/

Scattering of charged tensor bosons in gauge and superstring theories
, 2009 We calculate the leading-order scattering amplitude of one vector and two tensor gauge bosons in a recently proposed non-Abelian tensor gauge field theory and open superstring theory.

Energy Symmetry Breaking of Dirac and Weyl Fermions in Magnetized Spinning Conical Geometries
Advanced Theory and Simulations, Volume 8, Issue 10, October 2025.Exact solutions for relativistic fermions in magnetized, spinning conical geometries reveal defect‐induced symmetry breaking between fermion and antifermion energies. Energy levels depend on the magnetic field, background geometry, and fractionalized spin. When the defect's spin dominates, quantum effects diminish.
