neutrinoenes

Neutrinoenes are a hypothetical class of elementary particles that are theorized to be composed of neutrinos. The concept of neutrinoenes arises from attempts to reconcile the known properties of neutrinos, such as their very small mass and weak interactions, with potential deeper structures within the Standard Model of particle physics or in extensions thereof.

Unlike composite particles like protons and neutrons which are made of quarks, neutrinoenes, if they exist, would be made of leptons. The primary motivation for considering such particles is often related to understanding the origin of neutrino mass and exploring possible new symmetries in nature. Some theoretical models propose that neutrinos might not be fundamental but rather bound states of more fundamental constituents, and neutrinoenes could represent such a bound state.

The experimental search for neutrinoenes is extremely challenging due to the inherently weak interactions of neutrinos. Detecting a particle composed of neutrinos would likely require observing subtle deviations in neutrino interactions or decays, or through indirect astrophysical signals. To date, there is no direct experimental evidence confirming the existence of neutrinoenes, and they remain a speculative concept within theoretical particle physics. Future experiments designed to probe neutrino properties with greater precision or to search for new particles might provide clues about their potential existence.
