String webs from field theory [PDF]
Journal of High Energy Physics, 2001 The spectrum of stable electrically and magnetically charged supersymmetric particles can change discontinuously as one changes the vacuum on the Coulomb branch of gauge theories with extended supersymmetry in four dimensions.

String scattering amplitudes and deformed cubic string field theory
Physics Letters B, 2018 We study string scattering amplitudes by using the deformed cubic string field theory which is equivalent to the string field theory in the proper-time gauge.

D-instantons, string field theory and two dimensional string theory [PDF]
Journal of High Energy Physics, 2021 In [4] Balthazar, Rodriguez and Yin (BRY) computed the one instanton contribution to the two point scattering amplitude in two dimensional string theory to first subleading order in the string coupling.

Gravitational Scattering Amplitudes and Closed String Field Theory in the Proper-Time Gauge [PDF]
EPJ Web of Conferences, 2018 We construct a covariant closed string field theory by extending recent works on the covariant open string field theory in the proper-time gauge. Rewriting the string scattering amplitudes generated by the closed string field theory in terms of the ...

Searching for continuous phase transitions in 5D SU(2) lattice gauge theory
Journal of High Energy Physics, 2021 We study the phase diagram of 5-dimensional SU(2) Yang-Mills theory on the lattice. We consider two extensions of the fundamental plaquette Wilson action in the search for the continuous phase transition suggested by the 4 + ϵ expansion.

Bootstrapping closed string field theory
Journal of High Energy Physics, 2023 The determination of the string vertices of closed string field theory is shown to be a conformal field theory problem solvable by combining insights from Liouville theory, hyperbolic geometry, and conformal bootstrap.

Fixing an ambiguity in two dimensional string theory using string field theory
Journal of High Energy Physics, 2020 In a recent paper, Balthazar, Rodriguez and Yin found some remarkable agreement between the results of c = 1 matrix model and D-instanton corrections in two dimensional string theory.

Conformal defects from string field theory
Journal of High Energy Physics, 2021 Unlike conformal boundary conditions, conformal defects of Virasoro minimal models lack classification. Alternatively to the defect perturbation theory and the truncated conformal space approach, we employ open string field theory (OSFT) techniques to ...

Open string field theory with stubs
Journal of High Energy Physics, 2023 There are various reasons why adding stubs to the vertices of open string field theory (OSFT) is interesting: the stubs can not only tame certain singularities and make the theory more well-behaved, but also the new theory shares a lot of similarities ...
