Determinant Formula for the Octagon Form Factor in N=4 Supersymmetric Yang-Mills Theory / Kostov, Ivan ; Petkova, Valentina B. ; Serban, Didina
We present a closed expression for the octagon form factor which appears as a building block in a class of four-point correlation functions in N=4 supersymmetric Yang-Mills theory considered recently by Coronado. [...]

Quantum Computation as Gravity / Caputa, Paweł ; Magan, Javier M.
We formulate Nielsen’s geometric approach to circuit complexity in the context of two-dimensional conformal field theories, where series of conformal transformations are interpreted as “unitary circuits” built from energy-momentum tensor gates. [...]

Observation of an Excited Bc+ State / Aaij, R. ; Abellán Beteta, C. ; Adeva, B. ; Adinolfi, M. ; et al
Using pp collision data corresponding to an integrated luminosity of 8.5 fb1 recorded by the LHCb experiment at center-of-mass energies of s=7, 8, and 13 TeV, the observation of an excited Bc+ state in the Bc+π+π invariant-mass spectrum is reported. [...]

Experimental Approach to Search for Free Neutron-Antineutron Oscillations Based on Coherent Neutron and Antineutron Mirror Reflection / Nesvizhevsky, V. V. ; Gudkov, V. ; Protasov, K. V. ; Snow, W. M. ; et al
An observation of neutron-antineutron oscillations (nn¯), which violate both B and BL conservation, would constitute a scientific discovery of fundamental importance to physics and cosmology. [...]

Hadronic τ Decays as New Physics Probes in the LHC Era / Cirigliano, Vincenzo ; Falkowski, Adam ; González-Alonso, Martín ; Rodríguez-Sánchez, Antonio
We analyze the sensitivity of hadronic τ decays to nonstandard interactions within the model-independent framework of the standard model effective field theory. [...]

Observation of a Narrow Pentaquark State, Pc(4312)+, and of the Two-Peak Structure of the Pc(4450)+ / Aaij, R. ; Abellán Beteta, C. ; Adeva, B. ; Adinolfi, M. ; et al
A narrow pentaquark state, Pc(4312)+, decaying to J/ψp, is discovered with a statistical significance of 7.3σ in a data sample of Λb0J/ψpK decays, which is an order of magnitude larger than that previously analyzed by the LHCb Collaboration. [...]
