abstract
The PANDAX-4T and XENONnT experiments present indications of Coherent Elastic Neutrino Nucleus Scattering (CE$\nu$NS) from ${}^{8}$B solar neutrinos at 2.6$\sigma$ and 2.7$\sigma$, respectively. This constitutes the first observation of the neutrino "floor" or "fog", an irreducible background that future dark matter searches in terrestrial detectors will have to contend with. Here, we first discuss the contributions from neutrino-electron scattering and from the Migdal effect in the region of interest of these experiments, and we argue that they are non-negligible. Second, we make use of the recent PANDAX-4T and XENONnT data to derive novel constraints on light scalar and vector mediators coupling to neutrinos and quarks. We demonstrate that these experiments already provide world-leading laboratory constraints on new light mediators in some regions of parameter space.

Flavor specific chiral $U(1)_X$ framework for explaining the ATOMKI anomaly
A gauged, flavor-specific U(1)_X two-Higgs-doublet model can realize the axial-vector Z' couplings needed to explain the ATOMKI 8Be and 4He anomalies while evading current bounds.

Prospect of the NUCLEUS Experiment at Chooz for Coherent Elastic Neutrino-Nucleus Scattering and New Physics Searches
Assuming the low-energy background can be eliminated, a 7-gram NUCLEUS detector at Chooz is projected to see coherent neutrino-nucleus scattering at 4.7σ in one year and to set competitive bounds on new neutrino interactions.

Testing light and heavy vector mediators with solar CE$\nu$NS measurements
Combined solar CEνNS data from XENONnT, PandaX-4T, and LZ yield competitive constraints on vector NSI and light mediators and a weak mixing angle measurement at low momentum transfer.

New light mediators and the neutrino fog: Implications from XENONnT nuclear recoil data
Light-mediator couplings are constrained more strongly when they attach to dark matter than to neutrinos, and the neutrinofog in xenon detectors is shifted and deformed under both scenarios.

Neutrino fog in the light dark sector: the role of isospin violation
In a U(1)' dark sector model, isospin-violating couplings shift both the neutrino floor and the DM exclusion bound, changing the window for light dark matter discovery.

Sub-GeV Dark Matter Under Pressure from Direct Detection
PandaX-4T S2-only data yields world-leading sub-GeV dark matter-electron scattering limits for heavy mediators in the 20-200 MeV range, although the result largely overlaps with the collaboration's own just-released analysis.
