DESCRIPTION:Speakers: Ekaterina Dmitrieva (INR RAS)\nWe investigate the pr
 oduction of millicharged particles (mCPs) by the Schwinger mechanism in th
 understorms in the atmospheres of different planets in the Solar system. W
 e consider a thundercloud as a giant capacitor that can be discharged in t
 wo ways: either by lightnings or by mCP production. Taking into account th
 e observation of lightning strikes\, we establish the constraints on the c
 harge and mass of mCPs. We examine two types of cloud configurations: a si
 mple arrangement of two clouds\, and a more complex layered structure that
  gives rise to potential wells. In the latter case\, we take into account 
 the effects of Bose enhancement for scalar mCPs\, and Pauli blocking for f
 ermionic ones. \n We use the observational data of planetary atmospheres  
 obtained by satellite missions to establish constraints on the charge and 
 mass of mCP particles. The best constraints came from the observation of t
 hunderstorms in Saturn's atmosphere under an assumption of layered cloud s
 tructure: we obtain a lower limit on the charge of $10^{-24}$ for bosonic 
 mCPs. These constraints for bosons are\, to the best of our knowledge\, th
 e best in the literature.\n\nhttps://indico.particle.mephi.ru/event/626/co
