Investigating Neutrino Interaction with Electron with Pythia

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of using Pythia, an event generator, to simulate neutrino interactions with electrons. Participants explore the capabilities of Pythia in the context of high-energy physics and suggest alternative software for generating relevant events.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Chen inquires whether Pythia can generate events involving neutrino interactions with electrons.
  • Some participants clarify that Pythia is an event generator developed by CERN using the Monte Carlo method.
  • One participant notes that Pythia primarily focuses on high-energy proton-proton and proton-antiproton collisions, suggesting it may not be suitable for neutrino interactions.
  • Another participant mentions that while Pythia has broad capabilities, it may not be able to perform the specific simulation Chen is interested in.
  • MadGraph and CalcHEP are proposed as alternative tools that might better serve Chen's needs, especially for Standard Model results or custom model building.

Areas of Agreement / Disagreement

There is no consensus on whether Pythia can fulfill Chen's request, with some participants expressing skepticism about its applicability to neutrino interactions while others suggest alternative software options.

Contextual Notes

Participants highlight the limitations of Pythia in simulating processes involving neutrinos, noting its focus on specific collision types. There is an acknowledgment of the need for alternative software for generating relevant events.

Hi,
I'm Chen.

Recently I was trying to study the neutrino interaction with electron.

Question:

can Pythia generate the event of ( e , neutrino ->...) ?

if so, please help me for input program.

thanks

Chen

What is Pythia exactly?
 
it is an event generator
written by Cern using montecarlo method

Well, I was going to say that the majority of its main authors are at Fermilab, but checking I see that only two of five are at Fermilab, and there is even one at CERN (the other two are at Lund).

That page says,
The current release is focussed towards LHC and Tevatron applications, i.e. high-energy pp and pbarp collisions. Also e+e- and mu+mu- annihilation processes may be simulated, but not e.g. ep, gammap or gammagamma collisions.

PYTHIA and its ilk are concerned with e+e- and hadronic colliders, which do not involve neutrinos in the initial state, so I don't think you're going to have much luck. You may be able to find more directly relevant software listed http://theorie.physik.uni-wuerzburg.de/~ohl/lc/generators.html, but I would try starting with MadGraph, myself.
 
In my experience, Pythia can generally do absolutely anything other than whatever the specific thing you want it to do is...

Seriously though, MadGraph and CalcHEP are probably your best bets (provided you don't need to go beyond leading order). If you want Standard Model results, MadGraph is probably the better choice; but, if you need to build your own models, CalcHEP is often simpler.
