PDFs
Stefano Carrazza
Jan 1, 2012
The determination of the structure of the proton is achieved through the comparison of experimental measurements and theoretical predictions.
We study the parton substructure of hadrons by casting it as a peculiar form of pattern recognition problem in which the pattern is a parton distribution function (PDFs), and we present the way this problem has been tackled and solved.
The main topics covered by this research project are:
- A reliable determination of PDFs and its uncertainties
- The phenomenological impact of PDFs on particle physics measurements/observables
- Techniques for the determination and manipulation of PDFs.
