Non-supersymmetric heterotic strings on

Ivano Basile, Daniel Robbins, Hassaan Saleem

We analyze the stability properties of a family of anti-de Sitter flux compactifications of the tachyon-free non-supersymmetric heterotic string in ten dimensions. In contrast with…

A domain wall bound on anti-de Sitter vacua

Niccolò Cribiori, Antonia Paraskevopoulou, Thomas Van Riet

We consider anti-de Sitter flux vacua interpolated by flux-changing domain walls. Demanding that the tension of such a domain wall be above the ultraviolet cutoff of the effective…

Higher-Spin and Higher-Point Constraints on Stringy Amplitudes

Ivano Basile, Grant N. Remmen, Georgina Staudt

We employ multiparticle factorization to constrain deformations of tree-level open string amplitudes. Assuming minimal degeneracy among intermediate states of the same spin up thro…

On differential operators for scalar-scaffolded gluons

Jin Dong, Yong-Xiang Su, Dongyu Yang

Recently, based on the curve-integral formulation for stringy Tr amplitudes, a combinatorial formulation for Yang-Mills amplitudes has been proposed which describes gluons usi…

On Time-Evolution in Quantum Gravity

Lasha Berezhiani, Gia Dvali, Otari Sakhelashvili

We derive an explicit BRST-exact operator identity for the bulk Hamiltonian in quantum gravity, working within a BRST-invariant quantization of General Relativity, treated as a low…

-meson from topological properties of the electroweak vacuum

Gia Dvali, Archil Kobakhidze, Otari Sakhelashvili

We further scrutinize the evidence for a recently suggested pseudo-scalar particle, the electroweak -meson. Its existence is demanded by matching the removal of the weak…
