Photino

In this article, we are going to explore in depth the topic of Photino and its impact on modern society. Photino is a topic of great relevance today and has generated a lot of debate in different areas. Over the last few decades, Photino has become increasingly important, influencing both the way we relate to others and how we perceive the world around us. In this article, we will analyze different aspects related to Photino, from its historical origin to its relevance today. We will also examine the possible future implications of Photino and how it is shaping the world we live in.

A photino is a hypothetical subatomic particle, the fermion WIMP superpartner of the photon predicted by supersymmetry. It is an example of a gaugino. Even though no photino has ever been observed so far, it is one of the candidates for the lightest supersymmetric particle in the universe. It is proposed that photinos are produced by sources of ultra-high-energy cosmic rays.

Photino numbers

Photinos have a lepton number 0, baryon number 0, and spin 1/2. With an R-parity of −1 it is a possible candidate for dark matter. It mixes with the superpartners of the Z boson (zino) and the neutral higgs (higgsino) to form the neutralino.
