secolelor

Secolelor is a term used in speculative physics to denote a hypothetical elementary particle proposed as a carrier of a possible fifth fundamental interaction beyond the four known forces. In proposed models, a secolelor would mediate a new interaction and would couple to standard model particles with a strength that can vary between theories, potentially being very weak.

The name is a neologism created in theoretical discussions; there is no standardized etymology or universally accepted spelling beyond the term itself.

Proposed properties vary by model. Some scenarios treat the secolelor as a scalar boson, others as a vector boson. Masses are proposed to span a wide range, from very light to heavy scales, with couplings to ordinary matter constrained by laboratory experiments, astrophysical observations, and cosmological data. As a result, researchers describe a broad but restricted parameter space where secolelors could exist without contradicting current evidence.

History and status: The concept arose within discussions of hidden sectors, dark matter portals, and precision tests of gravity and the standard model. It has not been experimentally confirmed, and no consensus exists on its existence or on preferred properties.

Relation to other ideas: Secolelor is related to other beyond standard model concepts such as dark photons, axions, and sterile neutrinos. It is typically framed as a mediator rather than a dark matter particle, though some models link it to the dark sector. The term appears in multiple papers and discussions, but with varying definitions and degrees of acceptance.
