New dynamics from hidden sectors may manifest as long-range forces between visible matter particles. The well-known case of Yukawa-like potentials occurs via the exchange of a single virtual particle. However, more exotic behavior is also possible. We present three classes of exotic potentials that are generated by relativistic theories: (i) quantum forces from the loop-level exchange of two virtual particles, (ii) conformal forces from a conformal sector, and (iii) emergent forces from degrees of freedom that only exist in the infrared regime of the theory. We discuss the complementarity of spin-dependent force searches in an effective field theory framework. We identify well-motivated directions to search for exotic spin-dependent forces.

    hep-ph 2025-09 conditional novelty 5.0 of 10

    The cosmic neutrino background screens the neutrino-pair force between scalar dark matter particles for m_chi below the CnuB temperature, reshaping SIDM parameter space and eliminating Sommerfeld enhancement.
