Supersymmetry
An extension to the Standard Model that predicts many new particles, which have been searched for at the Tevatron and LHC.

Videos Mentioning Supersymmetry

Barry Barish: Gravitational Waves and the Most Precise Device Ever Built | Lex Fridman Podcast #213
Lex Fridman
A theoretical extension of the Standard Model of particle physics that proposes a relationship between bosons and fermions, but which does not seem to provide a solution for dark matter.

Avi Loeb: Aliens, Black Holes, and the Mystery of the Oumuamua | Lex Fridman Podcast #154
Lex Fridman
A proposed new symmetry in particle physics for which no experimental evidence has been found yet.

Cumrun Vafa: String Theory | Lex Fridman Podcast #204
Lex Fridman
A proposed symmetry that relates fundamental particles of two different classes: bosons and fermions. It was theoretically discovered through string theory.

Harry Cliff: Particle Physics and the Large Hadron Collider | Lex Fridman Podcast #92
Lex Fridman
A theory involving a new type of symmetry between force particles (bosons) and matter particles (fermions), which could stabilize the Higgs field at its observed value and predict dark matter.

Fermilab
An extension to the Standard Model that predicts many new particles, which have been searched for at the Tevatron and LHC.

What's Going Wrong in Particle Physics? (This is why I lost faith in science.)
Sabine Hossenfelder
A theoretical framework postulating that all fundamental particles have a partner particle. Initial models with similar masses were ruled out, and subsequent amendments with higher masses have also failed to yield experimental confirmation.
