Is there a sigma for unexplained hypothetical discoveries?
I recently read that the Koide formula relating electronic leptons rest masses is often considered to be numerologic, since unexplained, even though recent years experiment data tend to narrow the ...

${}$Higgs mechanism
Is is correct to say that, elementary particles have different masses, because they have different coupling strengths to Higgs field? And if yes. Does it make sense to question, why they have ...

Why are gluons massless as their range is finite?
The range of electromagnetic waves and gravitational force is infinity and the particles exchanged during these interactions are photons and gravitons respectively. Both are massless following the ...

What are the actual interactions between the Higgs field and fermions?
I have done a bunch of research regarding the Higgs field and Higgs boson but I keep running into issues when trying to understand how the interactions between the Higgs field and fermions occur. I ...

When particles began interacting with the Higgs field, what determined the specific numbers for their masses?
All up quarks and antiup quarks have the exact same mass of 2.3 MeV/c³, just as every instance of each particle also has an exactly set quantum for their mass, according to their kind.
But if the ...

How can we talk about the mass of $W^\pm$ bosons when they don't diagonalise the mass matrix?
In the electroweak lagrangian, after symmetry breaking we get $W^1_\mu,W^2\mu,W^3\mu$ and $B_\mu$ bosons. These fields don't however diagonalise the mass matrix $\frac{\partial^2V}{\partial\phi_i\...

Beta decay experiments suggesting that neutrinos are massless
It's known that in the kinetic energy spectra of electrons from the negative beta decays that at the end of the spectra some electrons are found to have a maximum energy that is equal to the energy ...

How does the oscillation of the Higgs field contribute to its role as mass-giver?
I read that the Higgs field is a pair of complex numbers at each point of spacetime, and since we know that the Higgs boson has a mass, I'm imagining that these complex numbers oscillate over time at ...

Mass matrix for inverse seesaw mechanism
I am having trouble in diagonalizing analytically the mass matrix associated to the inverse seesaw mechanism with lagrangian:
$L= -y_1\bar{L}\tilde{H}N_{R_1} - -y_2\bar{L}\tilde{H}N_{R_2} + N_{R_1}^...

How did scientist calculate Higgs boson mass without measurement?
First of all, let us write out the lagrangian of the Higgs field
$\mathcal{L}=\partial_\mu\bar{\varphi}\partial^\mu\varphi-\lambda(\bar{\varphi}\varphi-\frac{v^2}{2})^2$
This yields $m^2=\lambda v^2$. ...

Which particles do $W$ bosons interact with to gain mass?
Which particles interact with $W$ bosons to give them mass?
I am aware that Higgs particles alone are not responsible for the mass of other particles.
In non-mathematical terms which particles give ...

Is there a formula, which gives a relation to quark masses?
There're a plenty of formulas giving a relation to lepton masses - Koide formula, Brannen's extension and Baruta's formula. But is there a formula, which gives relation between quark masses?
P.S. Yes, ...

If quarks and electrons are both 0-dimensional, how can they have different masses?
If they are zero-dimensional but have different masses, wouldn't that have to suggest they have different densities meaning they are composed of different things?

Why does the Higgs Mechanism give different masses to different particles?
What makes a quark different from an electron in the "eyes" of the Higgs Field? Does it have to do with the specific values of hypercharge and isospin associated with these particles? What ...

Are all elementary massive particles distortions in the Higgs field? [closed]
I am confused, as I understand it, all elementary massive particles are sourcing from the Higgs scalar field thus are all distortions in the Higgs field. How this differs elementary from the old ...
