Beyond Ghosts: AI Illuminates Stable Gravity Theories
![The viability of a ghost-free and gauge-invariant theory hinges on a precise relationship between correction coefficients: the Weyl-squared coefficient [latex]\beta_{W^2}[/latex] must remain independent of the kinetic term [latex]X[/latex], consequently demanding that the Gauss-Bonnet coefficient [latex]\beta_{GB}[/latex] exhibit a linear dependence on [latex]X[/latex], thereby illustrating a coupled functional dependency essential for theoretical consistency.](https://arxiv.org/html/2604.16531v1/solutionspacevisualization.png)

![The study demonstrates, through Next-to-Leading-Order Electroweak calculations, that the decay distributions of the Higgs boson into dilepton and diquark final states - specifically [latex]h\rightarrow\ell^{\pm}\nu_{\ell}q\bar{q}^{\prime}[/latex] and [latex]h\rightarrow\ell^{+}\ell^{-}q\bar{q}[/latex] - exhibit predictable ratios between Next-to-Leading-Order and Leading-Order approximations when mapped onto the [latex]m_{W_{low}}-m_{W_{high}}[/latex] and [latex]m_{Z_{low}}-m_{Z_{high}}[/latex] planes, thereby validating the theoretical framework for precision Higgs physics.](https://arxiv.org/html/2604.16218v1/x16.png)
