Role of IR-Improvement in Precision LHC/FCC Physics and in Quantum Gravity / Ward, Bennie F.L. (Baylor U.) ; Jadach, S. (Cracow, INP) ; Placzek, W. (Cracow, INP) ; Skrzypek, M. (Cracow, INP) ; Was, Z.A. (Cracow, INP) ; Yost, S.A. (Citadel Military Coll.)
IR-improvement based on amplitude-level resummation allows one to control unintegrable results in quantum field theory with arbitrary precision in principle. We illustrate such resummation in specific examples in precision LHC and FCC physics and in quantum gravity..

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. In the previous papers we have found, that multi-dimensional signatures of the tau^pm to pi^pm pi^0 nu and tau^pm to 3pi^pm nu decays can be used to distinguish between scalar and pseudoscalar Higgs state.

FCC Tau Polarization / Banerjee, S (Louisville U.) ; Was, Z (Cracow, INP)
SM parameters, such as thetpolarisation can be measured very precisely in $\tau$ decays. The phenomenology is quite similar to that of measurement of the $A_{\mathrm{FB}}$ parameter of the SM [1].Details of the $\tau$ decay spectrum, as well as a good understanding of associated uncertainty, play an important role in this measurement of polarisation, because the spin of the $\tau$ lepton is not measured directly..

Deep Learning Approach to Measurement of Higgs Boson CP in the $H\rightarrow \tau \tau $ Decay Channel / Barberio, Elisabetta (Melbourne U.) ; Le, Brian (Melbourne U. ; Cracow, INP) ; Richter-Was, Elzbieta (Jagiellonian U.) ; Was, Zbrigniew (Cracow, INP ; CERN) ; Zanzi, Daniele (Melbourne U.)
The measurement of the Higgs boson CP is amongst the most vital measurements in establishing the nature of the Higgs boson. Of the many decay channels, the ditau final state is one of the most sensitive channels due to the Yukawa coupling allowing access to a potential mixing between CP-even and CP-odd Higgs bosons. [...]

Machine learning classification: case of Higgs boson CP state in H to tau tau$ decay at LHC / Lasocha, K. (Jagiellonian U. ; CERN) ; Richter-Was, E. (Jagiellonian U.) ; Tracz, D. (Jagiellonian U.) ; Was, Z. (Cracow, INP) ; Winkowska, P. (AGH-UST, Cracow)
Machine Learning (ML) techniques are rapidly finding a place among the methods of High Energy Physics data analysis. Different approaches are explored concerning how much effort should be put into building high-level variables based on physics insight into the problem, and when it is enough to rely on low-level ones, allowing ML methods to find patterns without explicit physics model.
