The standard model of elementary particles (SM) suffers from various problems, such as power-law ultraviolet (UV) sensitivity, exclusion of general relativity (GR), and absence of a dark matter candidate. The LHC experiments, according to which the TeV domain appears to be empty of new particles, started sidelining TeV-scale SUSY and other known cures of the UV sensitivity. In search for a remedy, in this work, it is revealed that affine curvature can emerge in a way restoring gauge symmetries explicitly broken by the UV cutoff. This emergent curvature cures the UV sensitivity and incorporates GR as symmetry-restoring emergent gravity (symmergent gravity, in brief) if a new physics sector (NP) exists to generate the Planck scale and if SM+NP is Fermi-Bose balanced. This setup, carrying fingerprints of trans-Planckian SUSY, predicts that gravity is Einstein (no higher-curvature terms), cosmic/gamma rays can originate from heavy NP scalars, and the UV cutoff might take right value to suppress the cosmological constant (alleviating fine-tuning with SUSY). The NP does not have to couple to the SM. In fact, NP-SM coupling can take any value from zero to if the SM is not to jump from to the NP scale . The zero coupling, certifying an undetectable NP, agrees with all the collider and dark matter bounds at present. The seesawic bound , directly verifiable at colliders, implies that (i) dark matter must have a mass , (ii) Higgs-curvature coupling must be , (iii) the SM RGEs must remain nearly as in the SM, and (iv) right-handed neutrinos must have a mass . These signatures serve as a concise testbed for symmergence.

引力,跷跷板新物理学及其实验特征

基本粒子(SM)的标准模型存在各种问题,例如幂律紫外线(UV)敏感性,广义相对论(GR)的排除以及没有暗物质候选物。根据LHC实验,根据该实验,TeV域似乎没有新颗粒,开始使TeV规模的SUSY和其他已知的UV敏感性固化。为寻求补救措施,在这项工作中,发现仿射曲率可以通过恢复明显被紫外线截止破坏的量规对称性的方式出现。该出射曲率可治愈紫外线敏感性,并将GR用作恢复对称性的出射引力(对称引力),简而言之)是否存在一个新的物理扇区(NP)来生成普朗克尺度,以及SM + NP是否为费米-玻色平衡。该装置带有反普朗克SUSY的指纹,可预测重力为爱因斯坦(无更高曲率的项),宇宙/伽马射线可源自重的NP标量,并且UV截止值可能取正确的值来抑制宇宙常数(缓解使用SUSY进行微调)。NP不必耦合到SM。实际上,NP-SM耦合可以取从零到 如果SM不是要从 到NP规模零耦合证明了不可检测的NP,目前与所有对撞机和暗物质的边界都一致。该seesawic约束直接可验证在对撞机,意味着(ⅰ)暗物质必须有一个质量(ⅱ)希格斯曲率耦合必须是(iii)所述SM RGES必须如在SM几乎保持,和(iv)右旋中微子必须有一个质量这些签名可以作为简洁的测试平台。
