This is quantified using the asymmetry parameter $\eta = \frac{n_{baryon} - n_{antibaryon}}{n_{photon}}$ From cosmological measurements such as WMAP, $\eta …

Apr 26, 2019 · As I understand the matter, the existence or non-existence of up-down asymmetry in charmed baryon decays is not a trivial consequence of the physical laws that make up the …

Jul 18, 2017 · The equation you present is perhaps not the most intuitive, but it falls under the more general "forward-backward" ratio or asymmetry equation, which looks something like …

Feb 28, 2019 · Ideally the peaks should be symmetric so my question is what is the main origin of asymmetry in the peaks? My best guess is it is some small misalignment which means one …

May 6, 2024 · You should consider the asymmetry as coming more-fundamentally from the ultraviolet completion of electromagnetism into a non-Abelian Yang-Mills quantum field theory. …

May 7, 2015 · Could someone explain to me in simple terms what the asymmetry term means and how it is derived. I don't really want a full fledged mathematical derivation, but more the basic …

Jan 7, 2021 · Why this asymmetry? Well, that is how the magnetic field $\vec{B}$ is defined. Both $\vec{E}$ and $\vec{B}$ are not relativistically invariant and are different aspects of one …

May 7, 2019 · $\begingroup$ One thing I might add, just for completeness: the reason we see the idea of "groups" pop up when we're looking at symmetry is because group theory is …

Jun 2, 2020 · The same goes for baryon asymmetry. If you look only at the theory (i.e. no observational evidence) then there's very little a priori reason to favor matter over antimatter. …

We find particle hole symmetry (PHS) for example in superconductors, where you can consider the Bogoliubov-de Gennes (BdG) Hamiltonian as a mean-field approximation.
