Summary: This paper proposes a refined topological string correspondence for the expectation values of half-BPS Wilson loop operators in 5d N=1 gauge theory partition function on the Omega-deformed background. The authors provide the refined topological vertex method and the refined holomorphic anomaly equation method to compute the partition functions of 5d Wilson loops in both A- and B-models. With the exact results in the B-model, they recover the quantum periods of local P-1 x P-1 model and local P-2 model in the study of quantum geometry and give a refined generalization of A-period.

Summary: Null Wilson loops in N = 4 super Yang-Mills theory are dual to planar scattering amplitudes, and have hidden symmetries. By integrating over the insertion point, one can obtain information about the amplitude. The study of the Wilson loop with a Lagrangian insertion reveals its leading singularities and symmetry properties. Surprisingly, the conformal symmetry becomes an invariance when the Lagrangian insertion point is sent to infinity. The action of higher Yangian charges on the Grassmannian integral is investigated using integrability methods.

Summary: This study completes the program on perturbative approaches for N = 2 superconformal quiver theories in four dimensions by evaluating observables in the presence of Wilson loops using supersymmetric localization. Various calculations were done, including Wilson loop vacuum expectation values, correlators of multiple coincident Wilson loops, and one-point functions of chiral operators as superconformal defects. The analysis is extended to the most general case considering chiral operators and multiple Wilson loops scattered among the vector multiplets of the quiver, identifying twisted and untwisted observables to probe the AdS(5) x S-5 orbifold for possible holographic perspectives.

Summary: This study investigates the two-point correlators of local operator insertions in a system of two Wilson-Maldacena loops in N = 4 supersymmetric Yang-Mills theory on both sides of the AdS/CFT correspondence. By analyzing the holographic and field theory perspectives, the behavior and efficacy of the correlators are determined.

Summary: We study the two-point function of the stress-tensor multiplet of N = 4 SYM in the presence of a line defect, obtaining results up to next-to-leading order in the coupling constant using a combination of perturbation theory and defect CFT techniques. We present a closed-form formula for the defect CFT data and use our analysis to check against well-known data of N = 4 SYM, recovering correct anomalous dimensions and comparing one-point function results.

Summary: We study new 1/24 BPS circular Wilson loops in ABJ(M) theory, which interpolates between previously known 1/6 BPS loops and 1/2 BPS fermionic loops. Using a one-dimensional effective field theory approach, we compute the expectation values of these operators up to second order in perturbation theory. We find non-trivial β-functions for the parameters, triggering RG flows from a UV fixed point represented by the 1/6 BPS bosonic loop to an IR fixed point represented by a 1/2 BPS fermionic loop.

Summary: Exact formulas for circular Wilson loops in the N=4 and N=2* theories with gauge groups U(N) and SU(N) are derived, applicable in the limit of large k, small Yang-Mills coupling g, and any finite N. Closed analytic formulas are obtained for SU(2) and U(2) cases, while 1/k series expansions are asymptotic. Simple formulas for correlation functions between the k-symmetric Wilson loops and chiral primary operators are also provided.

Summary: In this study, we investigate the possible BPS Wilson loops in three-dimensional N = 4 Chern-Simons-Matter theory, focusing on loops involving only the gauge field and bilinears of the scalars. We classify these loops into different classes based on the number of preserved supercharges and analyze their symmetries.

Summary: We propose a systematic method to establish a relationship between the correlation function of operators on the curved Maldacena-Wilson line and the integrability data for the cusp anomalous dimension. The derivation requires careful treatment of UV divergences. Our method allows for deriving multiple constraints on integrals of multi-point correlation functions, connecting them with the integrability data for the generalised cusp anomalous dimension governed by the Quantum Spectral Curve. These constraints, in combination with the numerical conformal bootstrap, have been recently proven to be very powerful in providing stringent non-perturbative bounds on conformal data beyond the spectrum.

Summary: This article studies the fate of reparametrization invariance of Wilson loops under the RG flow, using large-N, strongly coupled CFTs and the holographic dual description. The results show that a cutoff in the holographic radial direction breaks conformal invariance and induces an effective defect action at the cutoff scale.

Summary: This paper studies line defects with large quantum numbers in conformal field theories. It first considers spin impurities in a free scalar triplet and the Wilson-Fisher O(3) model and reveals a rich phase diagram. A new semiclassical approach is developed to obtain these results. For the Wilson-Fisher model, an alternative description is proposed to study large spin impurities. Additionally, the paper also investigates Wilson lines in large representations of N = 2 superconformal field theories.

Summary: This paper generalizes Nakajima-Yoshioka's blowup formula to calculate the partition functions counting the spectrum of bound states to half-BPS Wilson loop operators in 5d (and 6d) supersymmetric field theories. The partition function factorizes into two Wilson loop partition functions under localization when a Wilson loop operator is placed on the blowup C-2 in the Omega-background. This structure provides a set of blowup equations for Wilson loop operators, with explanations on how to formulate and solve them to compute the partition functions. The idea is tested by explicitly calculating the Wilson loop partition functions in various 5d/6d field theories and comparing them against known results and expected dualities.

Summary: This paper classifies four-point local gluon S-matrices in arbitrary dimensions, explicitly listing the construction method for gauge groups SO(N) and SU(N) and showing its generalizability. The study involves combining non-symmetric four-point S-matrices of photons and adjoint scalars into permutation symmetric four-point gluon S-matrices, with explicit listings for various components and dimensions. Additionally, it presents local Lagrangians that generate the local gluon S-matrices for D >= 9 and discusses the Yang-Mills four gluon S-matrix in terms of basis structures.

Summary: In this paper, constraints imposed by unitarity and crossing symmetry on conformal theories in large dimensions are analyzed. The results show that under certain conditions, the four-point function of identical scalar operators in a unitary conformal theory resembles that of the generalized free field theory. Additional assumptions about the spectrum of light operators can further extend the applicability of these results.

Summary: In this paper, we propose a conformally covariant momentum space representation called the AdS S-matrix for CFT correlation functions. It reduces to the S-matrix in the flat space limit. We provide Feynman-like rules to compute the AdS S-matrix in 1/R perturbation theory and relate it to the Mellin space representation of the conformal correlators in 1/R perturbation theory.

Summary: The paper introduces a natural generalization of von Neumann entropy, called multi-entropy, that is symmetric with respect to multiple parties. It is demonstrated that for conformal field theories with holographic duals, the multi-entropy can be computed by the area of a soap-film anchored on the boundary. The paper also conjectures a quantum version of this prescription that considers the subleading corrections in GN.
