Naming of the Leptons - Find the Right Word

Click For Summary

Discussion Overview

The discussion revolves around the appropriate terminology for classifying leptons based on their transverse momentum in a research context, specifically when dealing with channels that produce three leptons. Participants explore various naming conventions and semantic considerations related to this classification.

Discussion Character

  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant seeks a term for the lepton with the smallest transverse momentum, suggesting possibilities like "following lepton" or "sub-sub-leading lepton."
  • Another participant proposes the term "third lepton," noting that the smallest transverse momentum lepton may not be well-defined due to the presence of additional lower-energy leptons from hadron decays.
  • A different viewpoint suggests that the opposite of leading could be "trailing" or "lagging," but these terms may not fit the context appropriately.
  • Another participant mentions a naming convention of "next to the subleading" as a potential alternative.
  • One participant references established terminology in particle physics, such as Leading Order (LO) and Next-to-Leading Order (NLO), as a more formal approach to naming.
  • Another suggestion is to consult a supervisor for guidance on terminology or to create a new term like "sub-sub-leading" and clarify its meaning in the research paper.

Areas of Agreement / Disagreement

Participants express differing opinions on the appropriate terminology, with no consensus reached on a single term for the lepton with the smallest transverse momentum. Various suggestions and considerations are presented, indicating a lack of established terminology in this specific context.

Contextual Notes

The discussion highlights the ambiguity in naming conventions for leptons based on transverse momentum, with participants acknowledging that the definition of the smallest transverse momentum lepton may vary depending on the presence of other lower-energy leptons.

Hi, I am currently an undergraduate student and I am writing my undergraduate research paper right now.

The thesis is about searching for heavy Majorana type neutrinos.

While writing the paper, I really need some 'right word' but I can't find it so let me explain it here, and it would be very grateful if someone tells me what the right word is.Let's say there is a channel whose final objects have 3 leptons (and other stuffs too).

We usually call the lepton with the biggest transverse-momentum 'leading lepton'.
And the second biggest 'sub-leading lepton'.However, I can't find the word for the smallest transverse-momentum.
Can anyone tell me a proper term for the lepton with smallest transverse-momentum?

Maybe... following lepton? or... sub-sub-leading lepton (since it has the smallest but also the third biggest momentum)?
Doesn't the right term exist??

The usual name is "third [particly type]". Here: third lepton.
There can always be more leptons at lower energy from hadron decays and so on, something with the smallest pT is not well-defined.
 
Just from a semantics point of view the opposite of leading is either trailing or lagging. But neither of these make sense in this context.
 
it would have been something like next to the subleading (my naming).
 
Sometimes we say leading, sub-leading, and sub-sub leading, though its nicer to use the Leading Order (LO) Next-to-Leading Order (NLO), Next-to-Next-to Leading Order (NNLO), etc.
 
Since it's a matter of word choice, you can ask your supervisor whether he knows of any such term... otherwise you can just use somekind of naming like "sub-sub-leading" (as Hepth mentioned above) like inventing one and explain in your text what you mean by it.
