Strong coupling expansion of $\frac{1}{2}$ BPS Wilson loop in SYM theory and 2-loop Green-Schwarz string in AdS $_{5} \times$ S $^{5}$

Matteo Beccaria, Stefan A. Kurlyand, Arkady A. Tseytlin

The exact localization result for the expectation value of the $\frac{1}{2}$ BPS circular Wilson loop in $N = 4$ SYM theory is given in the planar limit by the famous Bessel func…

2-loop free energy of M2 brane in AdS $_{7} \times$ S $^{4}$ and surface defect anomaly in (2,0) theory

Matteo Beccaria, Stefan A. Kurlyand, Arkady A. Tseytlin

A $\frac{1}{2}$ -BPS surface operator viewed as a conformal defect in rank $N$ 6d (2,0) theory is expected to have a holographic description in terms of a probe M2 brane wrapped on…

2-loop scattering on superstring and supermembrane in flat space

M. Beccaria, R. Roiban, A. A. Tseytlin

We consider the S-matrix of transverse scalar excitations on an infinite $D = 10$ GS superstring and $D = 11$ supermembrane in flat target space. We compute the 4-particle scattering a…

On non-planar ABJM anomalous dimensions from M2 branes in AdS $_{4} \times S^{7} / Z_{k}$

Matteo Beccaria, Stefan A. Kurlyand, Arkady A. Tseytlin

Planar parts of conformal dimensions of primary operators in $U_{k} (N) \times U_{- k} (N)$ ABJM theory are controlled by integrability. Strong coupling asymptotics of planar dimensions…

Non-planar corrections to ABJM Bremsstrahlung function from quantum M2 brane

Matteo Beccaria, Arkady A. Tseytlin

As was shown in arXiv:2303.15207, the leading large $N$ , fixed $k$ correction in the localization result for the expectation value of the $\frac{1}{2}$ -BPS circular Wilson loop in…

Semiclassical quantization of M5 brane probes wrapped on $AdS_{3} \times S^{3}$ and defect anomalies

Matteo Beccaria, Lorenzo Casarin, Arkady A. Tseytlin

We consider two supersymmetric M5 brane probe solutions in $AdS_{7} \times S^{4}$ and one in $AdS_{4} \times S^{7}$ that all have the $AdS_{3} \times S^{3}$ world-vo…
