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 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 side of the peak will receive a higher intensity and vice versa, which is consistent with all of my peaks, however I'm not sure if this is definitely it
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)?
Introducing time asymmetry in the Boltzmann equation By asserting that it was acceptable to ignore these correlations in the population at times after the initial time, Boltzmann had introduced an element of time asymmetry through the formalism of his calculation
cosmology - Why is it assumed that the Big Bang produced equal parts . . . Up to now, none B-violation process has ever been seen, CP-violations are actually present in the theory of the standard model The last condition is only necessary to state that the process giving rise to the baryon asymmetry is not an equilibrium process, otherwise there would be compensations to counter the asymmetric process
What does the term inversion symmetric mean? From a geometrical point of view, inversion symmetry is equal to point symmetry, i e invariance under a point reflection Shapes (a), (b) and (d) are invariant under point reflection if the point of inversion is located directly between the two arrows Hence, they are inversion symmetric Shape (c) is not point inversion symmetric
Baryon asymmetry still going on - Physics Stack Exchange Baryon asymmetry Why do we believe baryon asymmetry? Why does matter-antimatter asymmetry only refer to baryon asymmetry? How does inflation get rid of initial Baryon asymmetry (if any)? None of these answer my question: Is Baryon asymmetry over, or is it still going on in the observable universe?
Why are flight feathers asymmetric? - Physics Stack Exchange «the more forwards-facing the feather is in-flight, the more vane-asymmetry it displays» I see My pionus doesn't have isolated finger-like feathers, as those are characteristic of soaring birds But I note that his shed flight feathers are still asymmetric
