Fermion Definition

Rather than define Fermions as simply obeying the Pauli Exclusion Principle, would it perhaps make sense to define them as obeying Fermi-Dirac Statistics instead? This is a more general definition, and the fact that they are subject to the Pauli exclusion principle is a natural consequence of following Fermi-Dirac statistics. It would also provide convenient symmetry since Bosons are defined in the opposite panel as following Bose-Einstein Statistics. Agozer (talk) 15:15, 20 August 2017 (UTC)

I made this scheme in order to better stress the defining characteristics of the different kinds of elementary particles. It has been around for quite a long time so I accept it is useful not only for me. However, I am an enigineer, not a physicist. So feel free to modify the template if you feel your edits will make it more useful. Gazibara (talk) —Preceding undated comment added 08:46, 22 August 2017 (UTC)

Thanks for your reply. I think my suggestion would be helpful simply because it is a more general definition (and in fact where the name Fermion comes from), so I'll make the change. Agozer (talk) 21:06, 29 August 2017 (UTC)

Is there an editor for this kind of chart? ♆ CUSH ♆ 02:24, 11 February 2019 (UTC)

Gauge Bosons

This chart lists (when {{{SM}}} is empty) Graviton as the fourth kind of Gauge Boson, although hypothetical. A footnote states that whether Graviton is a Gauge Boson is unknown and that it has spin = 2, which makes it a tensor boson, while the other Gauge Bosons have spin=1, making them vector bosons. The chart defines Elementary Bosons as Gauge, with spin=1, or Scalar, with spin=0. These parts are contradictory: definitely in grouping Graviton under definition spin=1 but note states it has spin=2; and possibly in grouping Graviton as a Gauge Boson. Furthermore, the 4 kinds of Gauge Boson in the Standard Model are usually photons, W bosons, Z bosons, and gluons. W and Z bosons are often grouped since they are the force carriers of weak interaction (1 of 4 forces). I'm not sure the best way to address these contradictions in the chart, as there are multiple ways. To keep the hypothetical Graviton in the body of the chart, maybe have three branches of Elementary Bosons: Scalar (spin=0), Vector (spin=1) and Tensor (spin=2) [or (spin=±2)?]—Vector could be described as Gauge Boson (Force Carrier), and Tensor described as possibly Gauge. The Tensor branch could have dashed rather than solid lines as it is hypothetical. However, Gauge Boson is probably much more widely seen than (Elementary) Vector Boson... Also, either break the W and Z bosons only separate numbered lines, or don't number the bosons at all (and remove reference to "four" kinds). --DanTrent (talk) 13:14, 23 February 2020 (UTC)

The graviton

I didn't notice the change for quite a long time. I am not going to object to your notes, as I have stated previously I am an engineer, not a physicist. However, when {{{SM}}} is not empty, the chart becomes inconclusive: the title under Gauge bosons read "Four kinds" and immediately only three kinds of bosons follow. And with an empty {{{SM}}} it is clearly marked that the graviton is a hypothetical, not actual particle, and the added note about it makes this even clearer.

Recent changes

Hey @Headbomb: could you please explain why my changes are not an improvement?

I removed "four fundamental interactions" as this is technically wrong; not all gauge bosons can carry all four interactions. It is also redundant, as the list below already explains which gauge boson carriers what force. (Also WP:MOS discourages the use of small fonts.) I also split the gauge boson abbreviations and the forces into separate parentheses, as this would otherwise grammatically imply that the gauge boson abbreviations are forces (or the forces gauge boson abbreviations). The abbreviations of all other particles are right of the particle's name – which is the grammatical standard – so I did the same with the gauge boson abbreviations. Furthermore, I linked force carriers to force carrier and hypothetical (below gravitation and next to graviton) to quantum gravity, as the gravitons are based on this theory. At last, as all gauge bosons are vector bosons and to provide a direct counterpart to the scalar bosons, I changed gauge bosons with vector bosons and four kinds with gauge bosons. But I would be open to change gauge bosons with four kinds of gauge bosons or something like that; and if this change is not acceptable at all, I would be ok with reverting it and mentioning vector bosons below the current position of gauge bosons.

It's rather irrelevant that "not all gauge bosons can carry all four interactions", no one expects them too. What's important is the force carriers are gauge bosons. Headbomb {t · c · p · b} 16:46, 28 July 2021 (UTC)

But my changes contravene with none of what you just said. So I would still like to know why they were reverted. Colonestarrice (talk) 17:19, 28 July 2021 (UTC)

@Headbomb: It has been three days now and I’m still waiting for a reply. Again, if you have any objections, I would gladly review them and make corrections where applicable, because I’m still having some major difficulties right now, in finding out what exactly the disimprovements were. Colonestarrice (talk) 11:07, 31 July 2021 (UTC)

I really don't see what else needs to be said. The important thing is that those are gauge bosons, that they are vector bosons is nearly irrelevant. And you're inverting the hierarchy, putting 'gauge bosons' in line with 'three generations' and 'unique' instead of 'four kinds'. I've asked others at WT:PHYS to opine, because I don't know what else you want me to say. You've yet to make a case for why your changes are improvements.
