Why are we still measuring the mass of the W boson | Explainer

The W boson is a fundamental particle in physics in the Standard Model, which describes how particles and forces interact. The W boson is responsible for mediating the weak nuclear force, one of the four fundamental forces of nature alongside gravity, electromagnetism, and the strong nuclear force.

40 years since the discovery of the W boson, its measurement is still a hot topic. Small variations in its measured value could indicate the presence of new physics beyond the Standard Model.

In the video, we explain why this is the case.

He may be the best science communicator on this CERN channel. His analogy is always spot on. I still vividly remember his analogy of 'throwing a dice repeatedly in a rabbit hole to prove the existence of an illusive rabbit who is believed to favor the number of 3' to explain the bump on the curve that proves the existence of the Higgs Boson.

Amazing presentation of the boson's, very easy to understand. Great video.

[enricokine]

Grazie per quotata bellissima presentazione. Chiara ed interessante! 🔝👏🏻

[fmontpetit]

Very well explained. Thank you so much

[ShopperPlug]

would be nice if explained how exactly the measurements are taken, like what kind of sensors, hardware and devices used.

[pablovillasenor]

Thank you again Piotr! You are an amazing science communicator. Greetings from Mexico :)

[Czeckie]

good luck with measuring that w boson babes, i liked the explanation of overconstrainedness

[stefanocicala]

Perché 😊la trascrizione non è in italiano ? Grazie

[ChikkuGOfficial]

Can you answer it?How Antimatter is related to W Boson?

[shauninferno]

The edge of cube got a cube was new 🤔👍

[bjornfeuerbacher]

If I remember correctly, W bosons also can decay into a quark and an antiquark, which then both produce hadronic jets. Can't one get the mass of the W boson from the total energy contained in these jets?

[ValidatingUsername]

Can you verify how many neutrinos you’re measuring from background noise or are you blocking them out somehow?

[Slizexd]

Oh man, I need to study English more, I only understood half of what the man said.

[alish]

boson sounds weird, isnt it boson, its comoketly doesnt in any way imply to particle physics, the name must indicate to its mechanism at least or part of it, but can you tell me whats the relatjon between boson and decay, nothing, the W decay particle, without boson, make it bosonless

[MatrixVectorPSI]

So it seems a measurement of the neutrino is the actual holdup.

before the conspricy theroiest come Current scientific theories and understanding of particle physics do not support the feasibility of creating stable portals to other dimensions or events that could end the world through particle collisions.

[BadYossa]

Interesting vid. I've heard that W Bosons pop in and out of existence (if that is the right term? - I'm a Chef, not a physicist) more times per second than the number of seconds that have existed since the Big Bang. Is this a correct?

[whiteazero-nqox]

...hello..."what is best" ive heard it said ...

Why is D * π = C "over constrained?"

If you measure the circumference of a circle, and then measure its diameter, and then divide the circumference by the diameter, you will find the value of π. It's that simple. It's a ratio, constrained by the diameter of the circle. Give me the circle's Diameter That's all I need to compute a Circumference for that circle, but only if I use one and only one value -- the value known as π. The value is always 2.1415... This it's an irrational number that has been known and used for over 2, 000 years to satisfy the relationship of a diameter to a circumference.

Why isn't "constrained" an adequate term to describe this phenomenon? What does adding the descriptor 'over' add to anyone's understanding of this relationship?

L’EXPANSOLOGIE est la science de la diffusion relativiste de la dilatation de l’espace, ce qui permet d‘expliquer la récession des galaxies et le fond cosmologique (sans big bang, sans expansion de l’univers, sans création de l’univers, sans inflation, etc…).

L’EXPANSOLOGIE explique la masse manquante grâce à LA SURGRAVITE (la matière noire n’existe pas). Comme la mécanique newtonienne est toujours bonne (en 1/r2), la théorie MOND est donc fausse.

L’EXPANSOLOGIE explique (le retard de) l’accélération de l’expansion par effet de marée interstructure (et donc sans énergie sombre).

L’EXPANSOLOGIE explique la création de la matière dans les accélérateurs de particules grâce au PARTICULEX (et donc sans corde, ni brane, ni spineur, ni supersymétrie, ni quarks, ni tachyons, etc…).

L’EXPANSOLOGIE explique que l’antimatière n’a pas disparue grâce au NEUTRINO LI-NEOSPINAL.

L’EXPANSOLOGIE explique la raison de la vitesse finie de la lumière grâce au LI-NEOSPINEX.

L’EXPANSOLOGIE est IMPUBLIABLE car le spinex est HYPERCOMPLEXE.

L’EXPANSOLOGIE est EXOSCOLAIRE. Dès lors les accélérateurs de particules deviennent inutiles car les spinex sont définitivement INEXPERIMENTABLES.

L’EXPANSOLOGIE explique le fonctionnement de la charge, de la gravité quantique, de la constante 1/137, de la constante h, de l'antimatière… grâce au SPINEX.

L’EXPANSOLOGIE explique la « théorie du tout » grâce au spinex, au particulex, à l’expanso, au modèle des multistructures, etc.

L’EXPANSOLOGIE explique que les multivers sont des aberrations théoriques.

L’EXPANSOLOGIE ne peut être évaluée que par des SURINTUITIFS comme le furent Léonard de Vinci, Robert Hooke, Charles Darwin, Galilée, Maxwell, Einstein… (Les mathématiciens, les savants, les vulgarisateurs et les bons élèves n'auront jamais les capacités intuitives pour évaluer l’expansologie).

SANS L’EXPANSOLOGIE la physique est DEFINITIVEMENT BLOQUEE.

AVEC L’EXPANSOLOGIE la cosmologie se révèle être une pseudoscience.

AVEC L’EXPANSOLOGIE l’astronomie sera tôt ou tard inutile.
