 Deep Neural Network application: Higgs boson CP state mixing angle in $H \to \tau \tau$ decay and at LHC / Lasocha, K. (Jagiellonian U. ; CERN) ; Richter-Was, E. (Jagiellonian U.) ; Sadowski, M. (Jagiellonian U.) ; Was, Z. (Cracow, INP) The consecutive steps of cascade decay initiated by H to tau tau can be useful for the measurement of Higgs couplings and in particular of the Higgs boson parity.

 Dispersive and Absorptive CP Violation in $D^0- \overline{D^0}$ Mixing / Kagan, Alexander L. ; Silvestrini, Luca In the precision era, CP violation in $D-\bar D$ mixing is ideally described in terms of the dispersive and absorptive phases $\phi_f^M$ and $\phi_f^\Gamma$, parametrizing CP violation (CPV) in the interference of $D^0$ decays with and without dispersive (absorptive) mixing.
