Light ALPs (or hidden photons) predicted in these models can be viable candidates of dark matter, and may be produced via the decays of the SM Higgs boson and the (newly introduced) dark Higgs boson. Interestingly, these models exhibit similar properties and a search for invisible decays of the SM/dark Higgs boson may serve as a tool for a generic probe of all the scenarios. In this talk, after a brief introduction of the theoretical framework, I will discuss how we can probe the li ... 14:00 - 15:00 Weekly Seminar An amplification mechanism for low frequencies, small intensities magnetic field quantum bioeffects School NANO SCIENCES There have been a growing number of researches indicating the effect of extremely low-frequency electromagnetic field (ELF-EMF) on living organisms. Here we propose a mechanism to explain how interactions with energy dozens of magnitudes below kBT are not being masked by thermal noise. Grounded on the previously discovered phenomenon of "Radical Pair Mechanism" (RPM), first, we introduce a scheme that suggests how applying a low-intensity magnetic field of the order of a few tens of milliTeslas can alter the superoxide production rate at Qo site of mitochondrial cytochrome bc1. Next, a reaction-diffusion model was used to show ... |
