The Standard Model successfully describes the fundamental particles and their interactions through the electromagnetic, weak, and strong forces, but it has several significant shortcomings: 1. **Gravity**: The Standard Model does not incorporate gravity, which is described by General Relativity. A complete theory of quantum gravity remains elusive.
Hypothetical elementary particles are theoretical constructs in physics that have not yet been observed or confirmed experimentally. These particles are proposed to explain various phenomena in the universe or to extend our understanding of fundamental forces and matter.

Gravitons are expected to be massless and have a spin of 2.
Gauginos are hypothetical particles in the field of theoretical physics, specifically within the context of supersymmetry (SUSY).

The Majoron is a hypothetical particle that is associated with certain extensions of the Standard Model of particle physics, particularly in the context of theories that involve the violation of lepton number conservation. It is often discussed in relation to the phenomenon of neutrinoless double beta decay, which is a rare process that would provide evidence for the Majorana nature of neutrinos (i.e., neutrinos being their own antiparticles).
Photinos are hypothetical elementary particles predicted by some theories in particle physics, particularly those related to supersymmetry (SUSY). In these theories, every known particle has a corresponding "superpartner" that differs in spin by a half-unit. While the photon is a massless gauge boson with a spin of 1 that mediates electromagnetic interactions, the photino would be the supersymmetric partner of the photon and would have a spin of 1/2.
Preons are hypothetical particles that have been proposed as subcomponents of quarks and leptons, the fundamental building blocks of matter in the Standard Model of particle physics. The idea is that if preons exist, they could provide a deeper understanding of the structure of matter by explaining why quarks and leptons have the properties they do. The preon model suggests that quarks and leptons are not elementary particles themselves but rather composite particles made up of even smaller entities—preons.

Tachyons are hypothetical particles that are theorized to travel faster than the speed of light. The concept arises from certain solutions to the equations of special relativity, which suggest that if such particles exist, they would have some counterintuitive properties. For example, tachyons would have an imaginary rest mass and could never slow down to or below the speed of light. Tachyons have not been observed in experiments, and their existence remains purely speculative.
Continuous spin particles are theoretical constructs in quantum field theory that extend the concept of spin beyond the usual discrete values found in standard quantum mechanics. In conventional quantum mechanics, spin is quantized and can take specific values, such as \(0, \frac{1}{2}, 1, \) etc. However, continuous spin particles are characterized by having an infinite number of spin states that can take any value along a continuous spectrum.

Flavor-changing neutral currents (FCNCs) are processes in particle physics that involve a change in the flavor of a quark or lepton without the emission or absorption of a charged particle (such as a W or Z boson, which are responsible for charged currents). Instead, these processes are mediated by neutral particles, typically the Z boson or neutral Higgs bosons. In the Standard Model of particle physics, FCNCs are highly suppressed and can occur only at loop level (i.

The Rishon model is a theoretical framework in particle physics proposed by physicist Joseph Rishon in the 1970s. It presents a unique perspective on the fundamental building blocks of matter. In this model, Rishon suggests that quarks and leptons—the fundamental particles that make up protons, neutrons, and electrons—are not elementary themselves but are composed of more basic entities called "preons.
The Seesaw mechanism is a theoretical framework in particle physics that explains the small masses of neutrinos, which are fundamental particles involved in weak interactions. This mechanism is an extension of the Standard Model of particle physics and relates to the concept of lepton mixing and mass generation. In the Seesaw mechanism, it is proposed that there exist heavy neutrinos (sometimes called right-handed or sterile neutrinos) along with the known light neutrinos (the left-handed neutrinos).
Split supersymmetry is a theoretical framework in particle physics that modifies traditional supersymmetry (SUSY) by relaxing some of its constraints. In the context of high-energy physics, supersymmetry is a proposed extension of the Standard Model that posits a symmetry between fermions (particles that make up matter) and bosons (force carrier particles).
