Even-point multi-loop unitarity and its applications: exponentiation, anomalies and evanescence by John Joseph M. Carrasco, Nicolas H. Pavao

“…Abstract We identify novel structure in newly computed multi-loop amplitudes and quantum actions for even-point effective field theories, including both the nonlinear sigma model (NLSM) and double-copy gauge theories such as Born-Infeld and its supersymmetric generalizations. …”

Spurious long-range entanglement and replica correlation length by Zou, Liujun, Haah, Jeongwan

“…We also calculate the replica correlation functions for representative wave functions of Abelian discrete gauge theories and the double semion theory in 2D, to show that they decay abruptly to zero. …”

Symmetry enriched U(1) quantum spin liquids by Zou, Liujun, Wang, Chong, Senthil, T.

“…We classify and characterize three-dimensional U(1) quantum spin liquids [deconfined U(1) gauge theories] with global symmetries. These spin liquids have an emergent gapless photon and emergent electric/magnetic excitations (which we assume are gapped). …”

Symmetries in Quantum Field Theory and Quantum Gravity by Harlow, Daniel, Ooguri, Hirosi

“…Quantum field theory results we meet while assembling the necessary tools include continuous global symmetries without Noether currents, new perspectives on spontaneous symmetry-breaking and ’t Hooft anomalies, a new order parameter for confinement which works in the presence of fundamental quarks, a Hamiltonian lattice formulation of gauge theories with arbitrary discrete gauge groups, an extension of the Coleman–Mandula theorem to discrete symmetries, and an improved explanation of the decay $$\pi ^0\rightarrow \gamma \gamma $$ π 0 → γ γ in the standard model of particle physics. …”

Symplectic geometry of conical symplectic resolutions by Zivanovic, F

“…So far, they have been considered in representation theory, algebraic and differential geometry, and also in theoretical physics as they arise from certain supersymmetric gauge theories. However, much of their symplectic geometry is unexplored. …”

Geometric insights from supergravity in the AdS/CFT correspondence by Perez Ipina, J

“…We also discuss the supersymmetric and extremal limits of these solutions and compute the entropy of these black holes, arguing that it should be possible to derive it from certain $\mathcal{N}=2$, $d=3$ quiver gauge theories compactified on a spinning spindle with magnetic flux.…”

Structure of Chern-Simons scattering amplitudes from topological equivalence theorem and double-copy by Yan-Feng Hang, Hong-Jian He, Cong Shen

“…Abstract We study the mechanism of topological mass-generation for 3d Chern-Simons (CS) gauge theories, where the CS term can retain the gauge symmetry and make gauge boson topologically massive. …”

Novel method to reliably determine the QCD coupling from R uds measurements and its effects to muon g − 2 and α M Z 2 $$ \alpha \left({M}_Z^2\right) $$ within the tau-charm energy... by Jian-Ming Shen, Bing-Hai Qin, Jiang Yan, Sheng-Quan Wang, Xing-Gang Wu

“…When calculating the fixed-order perturbative QCD (pQCD) approximant of R uds, its effective coupling constant α s Q ∗ 2 $$ {\alpha}_s\left({Q}_{\ast}^2\right) $$ is determined by using the principle of maximum conformality, a systematic scale-setting method for gauge theories, whose resultant pQCD series satisfies all the requirements of renormalization group. …”

Classifying gauge anomalies through symmetry-protected trivial orders and classifying gravitational anomalies through topological orders by Wen, Xiao-Gang

“…In this paper, we systematically study gauge anomalies in bosonic and fermionic weak-coupling gauge theories with gauge group G (which can be continuous or discrete) in d space-time dimensions. …”

Analytic bootstrap for perturbative conformal field theories by Henriksson, J

“…We study in similar depth conformal gauge theories in four dimensions, where we find a five-parameter solution for the most general form of the one-loop four-point correlator of bilinear scalars. …”
