12:00 - 11:00 Journal Club: Experiment & Phenomenology – meeting Magnetobaryogenesis in the presence of weak sphalerons from overlapping transient fluctuations in temperature and vorticity School PARTICLES AND ACCELERATORS Abstract: We show how the temperature-dependent chiral vortical effect can generate hypermagnetic fields and matter-antimatter asymmetries, in the symmetric phase of the early Universe, in the temperature range $100^n GeV^n leq T leq 10^n TeV^n$, even in the presence of the weak sphaleron processes. We take into account all perturbative chirality-flip processes, as well as the nonperturbative Abelian and non-Abelian anomalous effects. By considering the resulting constraints and conservation laws in the plasma, we reduce the number of required evolution equations. We also simplify the anomalous transport coefficients, accordingly. We t ... 16:00 - 18:00 Biweekly Seminar On the Theory of the Unity of Knower and Known School PHILOSOPHY On the Theory of the Unity of Knower and Known ... |
