| 11:00 - 12:00 Wednesday Weekly Seminar - meeting Dark Matter Beyond WIMPs School PARTICLES AND ACCELERATORS Abstract: The existence of nonbaryonic dark matter (DM) in the Universe is compelling, as suggested by astrophysical and cosmological observations. The most commonly assumed production mechanism for DM in the early universe corresponds to the weakly interacting massive particle (WIMP) paradigm, in which DM has mass and couplings at the electroweak scale. However, the current null experimental results and severe constraints on the natural parameter space are forcing us to search beyond the standard WIMP paradigm. In this talk, I will review alternative DM production mechanisms in the early universe, both thermal and non-thermal, ... 18:00 - 19:00 Physics Colloquium New experimental and theoretical information on the inner structure of proton School PHYSICS Date and time Wednesday, 21 Tir 1402 (12 July, 2023), 6 pm Link https://www.skyroom.online/ch/schoolofphysics/colloquium Abstract Proton is the main building block of visible matter. Although we have some information about its physical properties, its inner structure is not clear yet. There are also some puzzles regarding its spin, radii (charge, mass and mechanical), distribution of charge and magnetization inside as well as origin of its mass. In this talk I will discuss these issues introducing different form factors (electromagnetic, grav ... |
