All Tree Amplitudes of 6D (2,0) Supergravity: Interacting Tensor Multiplets and the K3 Moduli Space / Heydeman, Matthew ; Schwarz, John H. ; Wen, Congkao ; Zhang, Shun-Qing
We present a twistorlike formula for the complete tree-level S matrix of six-dimensional (6D) (2,0) supergravity coupled to 21 Abelian tensor multiplets. [...]

Causality and Loop-Tree Duality at Higher Loops / Runkel, Robert ; Szőr, Zoltán ; Vesga, Juan Pablo ; Weinzierl, Stefan
We relate an l-loop Feynman integral to a sum of phase space integrals, where the integrands are determined by the spanning trees of the original l-loop graph. [...]

Holographic Entanglement of Purification from Conformal Field Theories / Caputa, Pawel ; Miyaji, Masamichi ; Takayanagi, Tadashi ; Umemoto, Koji
We explore a conformal field theoretic interpretation of the holographic entanglement of purification, which is defined as the minimal area of the entanglement wedge cross section. [...]

Early Cosmological Period of QCD Confinement / Ipek, Seyda ; Tait, Tim M. P.
If the strong coupling is promoted to a dynamical field-dependent quantity, it is possible that the strong force looked very different in the early Universe. [...]

Evidence of a Resonant Structure in the e+eπ+D0D* Cross Section between 4.05 and 4.60 GeV / Ablikim, M. ; Achasov, M. N. ; Ahmed, S. ; Albrecht, M. ; et al
The cross section of the process e+eπ+D0D* for center-of-mass energies from 4.05 to 4.60 GeV is measured precisely using data samples collected with the BESIII detector operating at the BEPCII storage ring. [...]

Primordial Black Holes from the QCD Axion / Ferrer, Francesc ; Masso, Eduard ; Panico, Giuliano ; Pujolas, Oriol ; et al
We propose a mechanism to generate primordial black holes (PBHs) that is independent of cosmological inflation and occurs slightly below the QCD phase transition. [...]
