Understanding graphs generated by MadGraph

Dear Yvonne,

We do not have any tutorial for that level of question.
My first idea is to ask your supervisor if you your university provides some lectures on data analysis/ particle physics.

Cheers,

Olivier

This means that the value reported here correspond to the cross-section in a given bin, divided by the width of the bin.
This y-value is then not very sensitive to a rebinding.

Thanks. I appreciate it. why is it called sigma, though?
Thanks

sigma means cross-section.

I thought the sigma represent the standard deviation of the cross-section distribution and I couldn't make sense of it....thanks.
