In Supersymmetry, what is the relationship between bosons and fermions?

  1. Bosons and fermions are identical particles.

  2. Bosons and fermions have the same mass.

  3. Bosons and fermions have opposite spins.

  4. Bosons and fermions can be interchanged without changing the physics.


Correct Option: C
Explanation:

Supersymmetry posits that every boson has a corresponding fermion partner, and vice versa, with the two particles differing only in their spin.

What is the name given to the hypothetical particle that mediates supersymmetric interactions?

  1. Gluon

  2. Graviton

  3. Photon

  4. Sparticle


Correct Option: D
Explanation:

Sparticles are the hypothetical superpartners of known particles, such as the selectron (superpartner of the electron) and the squark (superpartner of the quark).

Which symmetry principle underlies Supersymmetry?

  1. Gauge symmetry

  2. Lorentz symmetry

  3. Supersymmetry

  4. Translational symmetry


Correct Option: C
Explanation:

Supersymmetry is a symmetry principle that relates bosons and fermions, postulating that every boson has a corresponding fermion partner, and vice versa.

What is the primary motivation for introducing Supersymmetry in physics?

  1. To explain the origin of mass

  2. To unify the fundamental forces

  3. To resolve the hierarchy problem

  4. To account for dark matter


Correct Option: C
Explanation:

Supersymmetry is primarily motivated by the need to address the hierarchy problem, which seeks to explain why the weak force is much weaker than the strong force.

Which of the following is a consequence of Supersymmetry?

  1. The existence of superpartners for known particles

  2. The unification of all fundamental forces

  3. The explanation of dark matter

  4. The resolution of the cosmological constant problem


Correct Option: A
Explanation:

Supersymmetry predicts the existence of superpartners for known particles, such as the selectron (superpartner of the electron) and the squark (superpartner of the quark).

What is the minimal number of supersymmetric generators required in a supersymmetric theory?

  1. 1

  2. 2

  3. 3

  4. 4


Correct Option: D
Explanation:

The minimal number of supersymmetric generators required in a supersymmetric theory is four, corresponding to the four different types of supersymmetry transformations.

Which of the following is NOT a type of supersymmetry transformation?

  1. Bosonic transformation

  2. Fermionic transformation

  3. Gauge transformation

  4. Lorentz transformation


Correct Option: D
Explanation:

Lorentz transformation is not a type of supersymmetry transformation. Supersymmetry transformations involve the interchange of bosons and fermions, while Lorentz transformations involve rotations and boosts in spacetime.

What is the name given to the hypothetical particle that mediates the force between superpartners?

  1. Graviton

  2. Gluon

  3. Photon

  4. Gravitino


Correct Option: D
Explanation:

The gravitino is the hypothetical particle that mediates the force between superpartners. It is the superpartner of the graviton, which mediates the force of gravity.

Which of the following is NOT a characteristic of supersymmetric theories?

  1. They predict the existence of superpartners for known particles.

  2. They unify all fundamental forces.

  3. They resolve the hierarchy problem.

  4. They violate Lorentz invariance.


Correct Option: D
Explanation:

Supersymmetric theories do not violate Lorentz invariance. Lorentz invariance is a fundamental symmetry of spacetime, and any theory that violates it would be inconsistent with our understanding of physics.

What is the name given to the symmetry that relates bosons and fermions in Supersymmetry?

  1. Gauge symmetry

  2. Lorentz symmetry

  3. Supersymmetry

  4. Translational symmetry


Correct Option: C
Explanation:

Supersymmetry is the symmetry that relates bosons and fermions. It posits that every boson has a corresponding fermion partner, and vice versa.
