| 11:00 - 12:00 Wednesday Weekly Seminar-google meet Searching for lepton flavor violating interactions at future electron-positron colliders School PARTICLES AND ACCELERATORS Abstract: Lepton flavor violating interactions are absent in the standard model but are expected in various beyond standard models. In this work, the potential of the future circular electron-positron collider to probe the four fermion lepton flavor couplings via the e+e- ? e ? process is revisited by means of an effective field theory approach. We provide constraints at 95% CL on the dimension-six Wilson coefficients including major sources of background processes and considering realistic detector effects at four expected operation energies of 157.5, 162.5, 240 and 365 GeV according to their corresponding integrated luminosities. We demonst ... 13:30 - 15:00 Weekly Seminar (Online) The interstellar medium through heavy molecules https://www.skyroom.online/ch/soa/weekly-seminar School ASTRONOMY The interstellar medium (ISM) is referred to as the ''gasses between stars'' within a galaxy. The ISM has quite various physics and chemistry, where to include the environments with a temperature of a few million Kelvin to pretty cool areas. Because of the young star activities in addition to the mass ejection of old stars, and of course, supernova explosions, several atoms, molecules, and compounds are found in the ISM. Neutral gases can be observed in this environment as well as very hot and highly ionized clouds. The ISM is the birthplace of all-stars of space and therefore its study tells us stories about a wide range of mysteries from th ... 14:00 - 15:00 Weekly Seminar Condensed Matter and Statistical Physics Group Active and Passive Magnetic Spheroids in Channel Flow Subject to External Field School PHYSICS Abstract: Active particles include a wide range of artificial self-propellers and biological swimmers that consume ambient free energy to facilitate their persistent, active, motion. Active Brownian particles constitute a basic model to approximate the swimming motion. These self-propelled particles are typically assumed to move at constant speed, while they are also subject to translational and rotational Brownian (thermal) noise and interaction forces from other surrounding objects in the medium. Study of active Brownian particles and their response to different forms of external stimuli, e.g., fluid flow and external chemical/ magn ... |
