Homework Statement


In my class I am doing a report on the Super String Theory and I have not been able to find what the letters and symbols represent in this equation I attached. If someone understands what they mean please help me. Thanks

Welcome to PF!

Your image is too blurry. Can you check it and upload a better one?

What kind of class is this for?

Where did you get the image of this equation?

Generally, there is a paper or some other article where the author lists the variables in the equations contained in the paper, along with a short description of what they mean.

it is for my science class and I found it under Wikipedia's Super string theory in the mathematics sub heading, the first equation.

IF you look at the reference it comes from Polchinski's book on String Theory on page 173. To me that means that there is a lot of math that is glossed over to get to this equation.

It mentions that computes scattering amplitudes which is key concept of quantum mechanics so investigating that would help you understand the big picture of the equation and how its used in predicting what you would see in an experiment.

Wiki has an article on it here:

A video talking about scattering:


This video talks about computing it although it may be over your head:
