What is pMSSM?

The Minimal Supersymmetric Standard Model (MSSM) is an extension to the Standard Model that realizes supersymmetry. MSSM is the minimal supersymmetrical model as it considers only “the [minimum] number of new particle states and new interactions consistent with phenomenology”.

What is supersymmetry and supergravity?

Supergravity is the theory that combines the principles of supersymmetry and general relativity. It naturally includes gravity along with the other fundamental forces (the electromagnetic force, the weak nuclear force, in turn already unified in the electroweak interactions, and the strong nuclear force).

Is supersymmetry a principle?

In a supersymmetric theory the equations for force and the equations for matter are identical. In theoretical and mathematical physics, any theory with this property has the principle of supersymmetry (SUSY).

Is supergravity a string theory?

Therefore, supergravity comes full circle and uses a common framework in understanding features of string theories, M-theory, and their compactifications to lower spacetime dimensions.

Does supersymmetry exist?

There are many different ways of achieving supersymmetry, all predicting different masses for the selectrons, the stop quarks, the sneutrinos and everybody else. To date, no evidence for supersymmetry has been found, and experiments at the Large Hadron Collider have ruled out the simplest supersymmetric models.

Is dark matter a supersymmetry?

One of the most complete theoretical frameworks that includes a dark matter candidate is supersymmetry. Dark matter is an unknown type of matter present in the universe, which could be of particle origin.

What is the difference between supersymmetry and Multiverse?

Supersymmetry is the valedictorian of the class. She’s got fundamental matter and forces that work just so in concert with each other to assure us that she is predictable and constant. Multiverse, on the other hand, basically slammed an energy drink, walked into the SATs and got a perfect score.

What is an axion particle?

An axion (/ˈæksiɒn/) is a hypothetical elementary particle postulated by the Peccei–Quinn theory in 1977 to resolve the strong CP problem in quantum chromodynamics (QCD). If axions exist and have low mass within a specific range, they are of interest as a possible component of cold dark matter.
