Probing electroweak symmetry breaking using vector boson scattering in ATLAS
/ Xu, Tairan (speaker) (University of Michigan (US))
Vector boson scattering (VBS) is a key process to study at the high-energy frontier. In particular longitudinal polarisation states of the boson have an intrinsic connection to the electroweak symmetry breaking and the Brout-Englert-Higgs mechanism [...]

Probing baryon-meson dynamics with $\Lambda^0_b$ and $\Xi^0_b$ decays to three-body states at LHCb
/ Garcia Martin, Luis Miguel (speaker) (EPFL - Ecole Polytechnique Federale Lausanne (CH))
Decays of beauty baryons to multibody states provide a unique window to search for intermediate resonances, including exotic states such as pentaquarks.
In this seminar, we present the first observation of the $\Xi^0_b \to J/\psi \Xi^-\pi^+$ decay and the most precise measurement of the branching fraction of the $\Lambda^0_b \to J/\psi \Xi^-K^+$ decay, using 5.4~fb$^{-1}$ of $pp$ collision data at $\sqrt{s} = 13$~TeV collected by the LHCb experiment. These decay channels offer new insights into the dynamics of baryon-meson systems [...]

FEL II
/ Hillert, Wolfgang (speaker)
The subject of this advanced course is a simplified treatment of the light amplification process in a free electron laser (FEL).
The first lecture deals with the so-called low gain FEL, where a “short” undulator is surrounded by an optical resonator. Starting with the calculation of the energy exchange between the electron beam and the radiation field, the ponderomotive phase is defined which remains constant when operating on resonance. [...]
