- cosmology - Baryon asymmetry - Physics Stack Exchange
Baryon asymmetry refers to the observation that apparently there is matter in the Universe but not much antimatter We don't see galaxies made of antimatter or observe gamma rays that would be prod
- Origin of XRD Peak Asymmetry - Physics Stack Exchange
I have been doing an introductory XRD experiment in which we measure the crystal spacing of a simple lattice (LiF) and as usual obtained data for intensity against two theta Ideally the peaks shou
- Gross asymmetry in Maxwell Equations - Physics Stack Exchange
The apparent asymmetry is due to how we usually today formulate the action principle: focusing on the Euler-Lagrange equations for , which give the source Maxwell equations, and forgetting about (taking for granted) the interpretation of the anti-symmetric derivative in terms of electric and magnetic field (the relation )
- big bang - Is the matter-antimatter asymmetry a logical or a . . .
Nonetheless, matter-antimatter asymmetry is a major motivation for physicists to look for new physics beyond the Standard Model that violate baryon number and lepton number in a CP violating way The impetus for new physics to "solve" this "problem" at high energies has been diminished somewhat, however, since the discovery of the Higgs boson
- What Does Up-Down Asymmetry Mean? - Physics Stack Exchange
So my question is, in the context of the article linked above, what does up-down asymmetry mean and what do particular numerical values of it mean (e g is the numerical value a ratio of something to something else, and if so, what)?
- Physical Interpretation of Forward-Backward Asymmetry
The idea being that any deviation of $\mathcal {A}$ from 0 would indicate such an "asymmetry", whatever is Since you ask in the context of particle physics, let's try to connect it to a practical example In the 1990's, people were colliding electrons and positrons and looking at the various outcomes (), particularly at pairs of muons and anti
- How does inflation get rid of initial Baryon asymmetry (if any)?
Why is it said that even if the baryon asymmetry existed as an initial condition, the asymmetry would have been destroyed by inflation How does inflation get rid of initial Baryon asymmetry (if an
- Rashba effect vs Dresselhaus effect (spin orbit coupling)
I understand that both are inversion breaking mechanisms - but rashba relates to structure inversion asymmetry, whereas Dresselhaus relates to bulk inversion asymmetry
