Non-analytic terms of string amplitudes from partial waves

Autor: Yu-tin Huang, Hynek Paul, Michele Santagata

Publikováno v: Journal of High Energy Physics, Vol 2024, Iss 11, Pp 1-36 (2024)

Abstract We describe a general formalism based on the partial-wave decomposition to compute the iterative s-channel discontinuity of four-point amplitudes at any loop order. As an application, we focus on the low-energy expansions of type I and II su

Exact large charge in N $$ \mathcal{N} $$ = 4 SYM and semiclassical string theory

Autor: Hynek Paul, Eric Perlmutter, Himanshu Raj

Publikováno v: Journal of High Energy Physics, Vol 2023, Iss 8, Pp 1-52 (2023)

Abstract In four-dimensional N $$ \mathcal{N} $$ = 4 super Yang-Mills theory with gauge group SU(N), we present a closed-form solution for a family of integrated four-point functions involving stress tensor multiplet composites of arbitrary R-charge.

Integrated correlators in N $$ \mathcal{N} $$ = 4 SYM via SL(2, ℤ) spectral theory

Autor: Hynek Paul, Eric Perlmutter, Himanshu Raj

Publikováno v: Journal of High Energy Physics, Vol 2023, Iss 1, Pp 1-70 (2023)

Abstract We perform a systematic study of integrated four-point functions of half-BPS operators in four-dimensional N $$ \mathcal{N} $$ = 4 super Yang-Mills theory with gauge group SU(N). These observables, defined by a certain spacetime integral of
