Does Matters Persist in Some Form Forever?
If all particles/matters eventually decay or annihilate in the distant future, will all the matter they once composed persist in some form forever, even after the universe reaches its (all scenerios ...

How di-quarks coupled with leptoquark can generate proton decay?
I am studying a BSM model where I add two scalar leptoquark, and apparently our group symmetry must be $SU(3)\times SU(2) \times U(1) \times \mathbb{P}_B$, where $\mathbb{P}_B$ acts as a discrete $\...

Is complete matter decay strictly necessary for Conformal Cyclic Cosmology to work?
I know that CCC is highly speculative and not widely accepted but I am curious about the constraints of this idea. As I understand it, CCC is the idea that in a massless universe, time and distance ...

Assuming that proton decay occurs, will all types of particles be dispersed without exception?
Proton decay is a theoretical possibility, as it is predicted to happen by some GUTs, so the proton may not be stable and could decay into lighter particles considering enormous time scales.
If proton ...

Supressing proton and neutron decay?
I was wondering whether the decay of neutrons and protons (if they happen to be able to decay, as it is predicted by some GUTs) could be avoided in some cases.
Let's begin with neutrons:
In principle ...

Experimental status/test possibilities for baryon number conservation in LHC?
Violation of baryon number is hypothesized e.g. for baryogenesis (more matter than antimatter from Big Bang) or Hawking radiation (baryons -> black hole -> massless radiation) - quite extreme ...

Effects of a hypothetical "proton-decay bomb" for a fictional story [closed]
I'm writing a science fiction story in which I need a devastating weapon of mass destruction that is far worse than nuclear bombs. For some reason, I'm fascinated by the idea of a "proton-decay ...

The energy axis for beta spectrum and Antineutrino spectrum
I am trying to plot an antineutrino spectrum and I was wondering whether the x axis has same range of energy values as the beta spectrum? I am taking the range of energy values to be from 0 upto ...

Neutrino Hypothesis for Beta Decay
Neutrino was discovered from the seemingly violation of conservation laws.
Supposedly, it was suprising to scientists, when they found electrons were emmited at various energies during beta decay ...

What is the half-life of deuterium if protons decay?
If we where to assume that protons decay and we know the half-life of protons, would it be possible to determine the half-life of deuterium?
If $^{1}$H (a single proton) has a half-life of, say, $10^{...

$\beta^{+}$ and $\beta^{-}$ decay processes
We know that electron cannot exist inside the nucleus for various reasons like its energy, angular momentum violation and etc. But these $\beta^{+}$ and $\beta^{-}$ processes occurs inside the nuclei ...

Neutronization process
How can I find the neutronization density for cold hydrogen plasma?
Does it happen within the fusion process of protons and electrons which yields neutrons and neutrino?

How can randomness occur in the case of radioactive decay ? Isn't there supposed to be a rule for everything that's driven by a non conscious mind? [duplicate]
I'm not trying to be unscientific here but i cannot wrap this around my head that scientifically anything can work randomly except a conscious mind which is capable of making a random decision. how ...

What is the half-life of isotopes that decay via electron capture, if they are stripped of their electrons?
If an isotope that undergoes decay via electron capture, like 7Be, loses ONE electron, how will its radioactive half life change? What about 2 electrons? And so on and so forth for heavier elements? ...

Anomalous baryon current in the Standard Model (SM) and the stability of free protons within the confines of the SM
In the Standard Model, the baryon number is not exactly conserved due to anomaly but the decay rate is extraordinarily small at ordinary temperatures. Does this make free protons unstable in the ...
