#CMSPAS: Measurements of inclusive and differential cross sections for Higgs boson production with decay to four leptons in proton-proton collisions at 13.6 TeV (CMS-PAS-HIG-25-015) https://cds.cern.ch/record/2958220 #Moriond #HiggsBoson

On an extension of Entangled Relativity with a positive cosmological constant We present a non-linear $f(R,\Lm)$ extension of General Relativity that possesses the full solution space of General Relativity with a positive cosmological constant $\Lambda$ for matter fields whose on shell Lagrangian satisfies $\Lm = T$, where $T$ is the trace of the stress-energy tensor. The theory belongs to the generalized Entangled Relativity family recently identified in the literature, and retains its Machian property that forbids the existence of vacuum solutions. Remarkably, despite being attracted toward General Relativity with a positive cosmological constant during the cosmological expansion of the Universe, the theory still involves one fewer fundamental parameter than General Relativity with $\Lambda$. Moreover, the dimensionful constant $\Lambda$ is replaced by a dimensionless parameter $\alpha$, from which an effective cosmological constant emerges in the field equations. Since the Universe is not entirely composed of matter fields satisfying $\Lm=T$ on shell---notably due to non-relativistic neutrinos that are such that $\Lm=0\neq T$ on shell---we argue that this framework naturally predicts small deviations from $\Lambda$CDM, potentially relevant for the interpretation of current cosmological tensions. For the same reason, the theory also lifts the degeneracy between different dark matter candidates and therefore can be used to make strong predictions on the dark matter sector.

I’m quite happy about this one. The result really does not look like anything familiar, even though it builds on recent papers in PLB and CQG, and on a result I presented two years ago at #Moriond.
