Chaotic-Integrable Transition in the Sachdev-Ye-Kitaev Model / García-García, Antonio M. ; Loureiro, Bruno ; Romero-Bermúdez, Aurelio ; Tezuka, Masaki
Quantum chaos is one of the distinctive features of the Sachdev-Ye-Kitaev (SYK) model, N Majorana fermions in 0+1 dimensions with infinite-range two-body interactions, which is attracting a lot of interest as a toy model for holography. [...]

Precision Study of ηγπ+π Decay Dynamics / Ablikim, M. ; Achasov, M. N. ; Ahmed, S. ; Ai, X. C. ; et al
Using a low background data sample of 9.7×105 J/ψγη, ηγπ+π events, which are 2 orders of magnitude larger than those from the previous experiments, recorded with the BESIII detector at BEPCII, the decay dynamics of ηγπ+π are studied with both model-dependent and model-independent approaches. [...]

Measurement of the Effective Weak Mixing Angle in pp¯Z/γ*+ Events / Abazov, V. M. ; Abbott, B. ; Acharya, B. S. ; Adams, M. ; et al
We present a measurement of the effective weak mixing angle parameter sin2θeff in pp¯Z/γ*μ+μ events at a center-of-mass energy of 1.96 TeV, collected by the D0 detector at the Fermilab Tevatron Collider and corresponding to 8.6 fb1 of integrated luminosity. [...]

Diffusion of Conserved Charges in Relativistic Heavy Ion Collisions / Greif, Moritz ; Fotakis, Jan. A. ; Denicol, Gabriel S. ; Greiner, Carsten
We demonstrate that the diffusion currents do not depend only on gradients of their corresponding charge density, but that the different diffusion charge currents are coupled. [...]

Limits on Light Weakly Interacting Massive Particles from the First 102.8 kg×day Data of the CDEX-10 Experiment / Jiang, H. ; Jia, L. P. ; Yue, Q. ; Kang, K. J. ; et al
We report the first results of a light weakly interacting massive particles (WIMPs) search from the CDEX-10 experiment with a 10 kg germanium detector array immersed in liquid nitrogen at the China Jinping Underground Laboratory with a physics data size of 102.8 kg day. [...]

Holographic QCD in the Veneziano Limit at a Finite Magnetic Field and Chemical Potential / Gürsoy, Umut ; Järvinen, Matti ; Nijs, Govert
We investigate QCD-like gauge theories at strong coupling at a finite magnetic field B, temperature T, and quark chemical potential μ using the improved holographic QCD model, including the full backreaction of the quarks in the plasma. [...]

Finite Density Condensation and Scattering Data: A Study in ϕ4 Lattice Field Theory / Gattringer, Christof ; Giuliani, Mario ; Orasch, Oliver
We study the quantum field theory of a charged ϕ4 field in lattice regularization at finite density and low temperature in 2 and 4 dimensions with the goal of analyzing the connection of condensation phenomena to scattering data in a nonperturbative way. [...]
