Calculating Cross Sections in Supersymmetry: A Comprehensive Guide

In summary, there are several sources available for learning about calculating cross sections in supersymmetric processes. One recommended book is "Theory and Phenomenology of Sparticles" by M. Drees, R.M. Godbole, and P. Roy, which includes calculations in chapter 6 and vertices in appendices A and B. Another useful resource is a paper by M. Drees and M.M. Nojiri, which explains how to use helicity states and partial wave amplitudes to calculate cross sections for WIMPs and neutralinos.

Hi there,

In particle physics there is famous books as Peskin's book " To Quantum Field Theory (Frontiers in Physics) " to learn matrix element amplitude and cross section calculations, like ee -> mu mu.

Are there similar references for supersymmetry to learn how to calculate the cross section of prototype supersymetric processes ?

Bests.

The ideas don't change much... you may just have more diagrams to add up and different vertices...
One book which has some calculations is : M.Drees, R.M. Godbole and P.Roy - Theory and Phenomenology of Sparticles (eg. ch.6 and I think it has the vertices in appendices A,B).

Also it depends on the context, eg for WIMPs neutralinos you can use the expansion in velocities and work with helicity states to deduce the partial wave amplitudes and cross sections from them.

1. What is supersymmetry and why is it important in physics?

Supersymmetry is a theoretical framework in physics that suggests the existence of a new symmetry between matter particles and force particles. This symmetry is important because it could help explain the hierarchy problem and provide a unified theory of all fundamental forces.

2. How are supersymmetry calculations performed?

Supersymmetry calculations involve using mathematical equations and computer simulations to predict the properties and behavior of supersymmetric particles. These calculations can be very complex and require advanced mathematical techniques.

3. What is the evidence for supersymmetry?

Although there is currently no direct experimental evidence for supersymmetry, there are several indirect pieces of evidence. For example, the existence of dark matter, which makes up a large portion of the universe, could be explained by supersymmetric particles.

4. What are the potential implications of proving supersymmetry?

If supersymmetry is proven to be true, it could have major implications for our understanding of the universe and the laws of physics. It could lead to a more complete theory of everything and potentially even new technologies and applications.

5. Are there any challenges in studying supersymmetry?

Yes, there are several challenges in studying supersymmetry. One major challenge is the lack of experimental evidence, which makes it difficult to test and validate theories. Additionally, the complexity of the calculations and the need for high-energy colliders can also be challenging for researchers.
