# Why is this specific question on particle physics being downvoted?

I just found and answered this question on why some particles are defined with square roots in their expressions. It has a bunch of downvotes, but the comments doesn't seem to clarify the reason for this. Also, there doesn't seem to be any close votes at the moment I'm posting this question.

After showing the question to friends, I noticed people without a background in particle physics might not be familiar with the notation and hence the question might seem quite unclear. Is this what is going on?

• You don’t need to be quite acquainted with quantum mechanics to understand the $\sqrt{2}$ factor: elementary notions of quantum mechanics should do this. Dec 31, 2021 at 15:54
• @ZeroTheHero I agree. My comment on the question saying "quite acquainted with QM" was because there was another comment saying "it is a common choice of normalization in QFT". While the factor itself is elementary QM, the term "QFT" might not be familiar (and I wanted to avoid mentioning it explicitly in that comment) Dec 31, 2021 at 17:49

1. I'd wager people who understand the question and know the answer expect anyone who cares about the technical notation for particle states and the $$\sqrt{2}$$ to understand how quantum mechanics and normalization works in the first place, i.e. the question jumps in "at the deep end" when it shouldn't and that's what it's being downvoted for.
