A How Can I Compare Parton Distribution Functions Without Data from Other Groups?

Click For Summary
To compare Parton distribution functions without access to other groups' data, it's essential to clarify the specific comparison method desired. While plotting multiple graphs in Mathematica is possible, the user seeks a way to evaluate their results against published data from groups like H1 and CTEQ without their Mathematica codes. Various groups present their results in different formats, and exploring their websites may yield useful data. The LHAPDF interface offers a comprehensive collection of relevant Parton distribution function sets, although it primarily supports Python rather than Mathematica. Utilizing these resources can facilitate meaningful comparisons of Parton distribution functions.

Parton distribution functions
Hello
I plotted the Parton distribution functions in Mathematica. Now I want to compare the graphs drawn with the graphs of other groups(xu and xd). How should I do this?
 
Physics news on Phys.org
Are you just asking how to plot several graphs in the same plot in mathematica? In that case I guess have a look here https://reference.wolfram.com/language/ref/Plot.html, the second syntax is what you want. Maybe I am not understanding what the question is?
 
I'm asking about comparing my results with other groups. I don't have other groups data such as H1, Cteq. I Plotted my results in Mathematica and I have other groups article. now, how can I compare these without their Mathematica codes?
 
If I type "graph of parton distribution functions" into Google, I get two million hits. OK, so they are not all useful, I am sure, but there are many dozens (probably hundreds) of such plots, and so I conclude that isn't what you want.

You need to be more descriptive in what you want - and this is the third time you've been asked.

Different groups publish their results in different formats, have you checked out their respective websites?

There is a universal interface called lhapdf https://lhapdf.hepforge.org/ where you will probably find any today relevant (proton) pdf set. I don't think they have a native Mathematica interface but the python one is pretty usable if I remember correctly.
 
Thread 'Some confusion with the Binding Energy graph of atoms'
My question is about the following graph: I keep on reading that fusing atoms up until Fe-56 doesn’t cost energy and only releases binding energy. However, I understood that fusing atoms also require energy to overcome the positive charges of the protons. Where does that energy go after fusion? Does it go into the mass of the newly fused atom, escape as heat or is the released binding energy shown in the graph actually the net energy after subtracting the required fusion energy? I...
Hello everyone, I am trying to calculate the energy loss and straggling of alpha particles with same energy, I used LISE++ to obtain the energy loss in every layer of the materials using Spectrometer Design of LISE++, but I can only calculate the energy-loss straggling layer by layer. Does anyone know the way to obtain the energy-loss straggling caused by every layer? Any help would be appreciated. J.
