Anomalies and discrete torsion in Type II and Type I worldsheet theories
Masashi Kawahira, Shotaro Kawanago, Shota Saito +1
We provide a comprehensive study of anomalies and discrete torsion in the worldsheet theories of Type II and Type I string theories on a general ten-dimensional target space. In th…
7-branes and Duality in Type 0B String Theory
Naoto Kan, Masashi Kawahira, Hiroki Wada
We investigate 7-branes in type 0B string theory, motivated by the recent proposal of Baykara, Dudas, and Vafa, which connects type 0B string theory with M-theory. On the -symme…
Deconfinement-Higgs continuity in adjoint Higgs model at finite temperature
Yui Hayashi, Masashi Kawahira, Hiromasa Watanabe
We study the finite-temperature phase structure of the four-dimensional adjoint Higgs model, focusing on a possible \textit{deconfinement-Higgs continuity}: the conje…
Emergent higher-form symmetry from type IIB superstring theory
Naoto Kan, Masashi Kawahira, Hiroki Wada
We investigate a higher-form symmetry in type IIB superstring theory, which possesses an symmetry. From the point of view of the low-energy effective field…
States and IR divergences in factorization algebras
Masashi Kawahira, Tomohiro Shigemura
In field theory, one can consider a variety of states. Within the framework of factorization algebras, one typically works with the natural augmentation state $\langle-\rangle_{\rm…
A concrete construction of a topological operator in factorization algebras
Masashi Kawahira
Factorization algebras play a central role in the formulation of quantum field theories given by Kevin Costello and his collaborators. In this paper, we propose a concrete construc…
