RE: Citizen science on Hive - simulation of a neutrino signal at CERN’s Large Hadron Collider with its uncertainties

in StemSocial2 years ago

In the framework of a collision at a particle collider, we make use of energy conservation to deduce the presence of neutrinos (and of any other invisible particle). This is achieved from an energy imbalance between the initial and the final state. Energy is conserved, so that if the energy of the initial state and that of the final state are different, then something invisible like a neutrino must carry energy away.

In the context of the present project, there is no final-state neutrino. We aim to grasp information on the model through one of its fully visible signatures ((heavy) neutrinos only appear as intermediate particles).

Are you calculating the amount of tau particles as well?

We could (and we should). However, there is for now not enough participants to the project to consider that signal too. It is only a matter of resources, as you can see... Maybe as a follow up... who knows?

Sort:  

Got it my friend, I guess you have also collected muon radiation profiles that comes out of the collider boundaries, I mean for safety even though you are doing it on a simulator no harm but in reality.

I understand resources for such projects often depends on tools and funds and satisfying the funding agencies for its utility.

Keep it up mate, you are on roll.

All safety tests have been made at the level of the LHC. There is a lot of documentation on this matter online (checkout CERN's website). Here, the idea is to trigger interest of experimenters to start a new analysis at an existing machine, and with existing data (so that if they got excited by the results, this can be started straight away).

Exactly. Although here, since we are running fully on Hive and with non-particle-physics actors, it is only a matter of human resources and not of money. Of course, I could do the exercise together with a student or a postdoctoral fellow. However, I have no one with enough free time in my group, so that we end up again at the problem of funding...

Cheers, and thanks for the chat :)
