A Catalog Of WISP Theories

A new preprint has a catalog (with references) of beyond the Standard Model theories that are "Weakly Interacting Slim Particle" (WISP) theories. Wikipedia explains the concept, which the abstract and introduction fail to do:

In particle physics, the acronym WISP refers to a largely hypothetical weakly interacting sub-eV particle, or weakly interacting slender particle, or weakly interacting slim particle – low-mass particles which rarely interact with conventional particles.

The term is used to generally categorize a type of dark matter candidate, and is essentially synonymous with axion-like particle (ALP). WISPs are generally hypothetical particles.

WISPs are the low-mass counterpart of weakly interacting massive particles (WIMPs).

The goal of the project is as follows: 

The search for physics beyond the Standard Model (SM) has led to the proposal of a vast landscape of theoretical frameworks. Among them, the family of Weakly Interacting Slim Particles (WISPs) has emerged as a particularly rich and versatile class of candidates, capable of addressing open questions in cosmology, astrophysics and particle physics. 

These particles, ranging from axions and axion-like particles to hidden photons, scalars, pseudoscalars, sterile neutrinos and spin-2 particles, illustrate the growing diversity of ideas within the field.  

The WISPedia is motivated by the need for a unified and systematic reference that organises this rapidly expanding model space. While numerous reviews exist on specific Weakly Interacting Slim Particle (WISP) candidates or experimental searches, the goal of this work is different: to provide a concise, model-oriented encyclopedia that outlines the essential ingredients of each framework– its particle content, interactions and phenomenological role, while pointing the reader toward the original literature and key complementary resources. Rather than serving as an exhaustive review, the WISPedia aims to serve as a quick, structured gateway into the theory landscape of light, weakly coupled particles. It also provides some information on bounds for each of them in a succinct way.

It's top level categorization is by the spin (a.k.a. intrinsic angular momentum a.k.a. "J") and parity of each kind of the Beyond the Standard Model (BSM) particles. 

It also has a very cute table of contents that summarizes some of the high points of each model. It uses emojis to annotate it. This cute legend is what inspired me to make this post, even though, like any catalog of BSM theories, the vast majority of theories discussed don't reflect reality and are "garbage theories" (not in the sense of being technically unsound, but in the sense of being ill-motivated and improbable).

This list of models currently in the catalog, envisioned as a Wikipedia-like or Particle Data Group-like encyclopedia of BSM particle theories that fit the (ill-defined) WISP paradigm, is as follows:
