The complement is ruled out on theoretical grounds alone, and part of that excluded region lies below present experimental limits.\n\nThe work takes the nonminimal coupling of the scalar multiplet to gravity, identifies the broken-phase Yukawa term, and integrates the flow from the UV scaling regime. The explicit translation of the basin of attraction into the observable plane is the concrete step that turns the fixed-point existence into a constraint on fifth forces.\n\nThis is new in the literature the abstract cites: prior bounds were empirical, while here UV completeness supplies an independent filter. The logic is direct once the fixed point and the flow are granted.\n\nThe soft spots sit in the RG implementation. The size and location of the wedge depend on the truncation of the effective action and on how the IR matching is performed. If those choices shift the fixed-point structure or the regular trajectories, the excluded region moves. The claim that the radial mode universally mediates the correction also rests on the model setup rather than a general proof.\n\nThe paper is aimed at people who want theoretical priors on fifth-force searches from quantum-gravity considerations. A reader already working with asymptotic-safety methods or planning next-generation torsion-balance or atom-interferometer runs will see the direct link.\n\nIt deserves peer review. The mapping is falsifiable in principle and connects two fields without internal contradiction, so the numerics and truncation dependence are worth a referee's time.","headline":"UV completeness in this O(N) scalar-tensor model carves the allowed fifth-force parameters down to a narrow wedge in the (α, λ) plane.","tokens_in":2222,"tokens_out":414,"would_cite":false,"duration_ms":17194,"reading_group":"maybe","serious_thinker":"yes","would_accept_peer_review":true},"rs_alignment":null,"lean_confirmation":null,"pith_extraction":{"msc":[],"pacs":[],"model":"grok-4.3","headline":"UV completeness restricts fifth-force parameters to a narrow region in scalar-tensor gravity","keywords":["scalar-tensor gravity","fifth force","renormalization group","UV completeness","Yukawa correction","O(N) scalar multiplet","asymptotic safety"],"falsifier":"Detection of a fifth force with parameters (α, λ) lying outside the narrow UV-allowed band would show that no regular trajectory reaches the assumed UV scaling regime.","tokens_in":2569,"feed_emoji":"","tokens_out":650,"duration_ms":23424,"temperature":0.7,"pith_summary":"The paper examines an O(N) scalar multiplet nonminimally coupled to gravity and tracks its renormalization-group flow near an interacting UV-complete scaling regime.
