A bstract It has been shown that a special set of three-point amplitudes between two
massive spinning states and a graviton reproduces the linearised stress-energy tensor for a …

A bstract We propose a covariant technique to excavate physical bosonic string states by
entire trajectories rather than individually. The approach is based on Howe duality: the …

We construct an infinite class of new ultraviolet-complete four-graviton scattering amplitudes
that reduce to Einstein gravity at low energies, vanish at high energies, are meromorphic …

Avatars of T‐duality within Sen's formalism for self‐dual field strengths in various dimensions
are studied. This formalism is shown to naturally accommodate the T‐duality relation …

In this Letter, we present the α′-exact background equations of motion of the bosonic chiral
string (also known as Hohm-Siegel-Zwiebach model), with the spin-two ghost fields …

In this work we present the $\alpha'$-exact background equations of motion of the bosonic
chiral string (also known as Hohm-Siegel-Zwiebach model), with the spin two ghost fields …

We extend the left-handed string formalism at one-loop level to focus on only the infrared
limit, where the Green's function for the left-handed string is expanded around the cusp of …

The chiral string without a singular gauge limit is argued to have the same critical dimension
as its corresponding conventional closed string. Thus, its central charge would be the same …

We explore two emerging topics in string theory: left-handed string amplitudes and q-
deformed open string amplitudes. First, we extend the formalism for left-handed strings …

A new set of boundary conditions for string propagators is proposed in this paper. The
boundary conditions are parametrized by a complex number $\lambda $. Under these new …
