The impact of nuclear effect modeling on the cross-section ratio $\nu_e/\nu_\mu$ and its impact for futrue measurements of CP violation / Dieminger, T (Zurich, ETH) ; Dolan, S (CERN) ; Sgalaberna, D (Zurich, ETH) ; Nikolakopoulos, A (Fermilab) ; Dealtry, T (Lancaster U.) ; Bolognesi, S (IRFU, Saclay) ; Pickering, L (Royal Holloway, U. of London) ; Rubbia, A (Zurich, ETH)
Long-baseline (LBL) neutrino oscillation experiments search for Charge-Parity (CP) violation in the leptonic sector by precisely measuring the $\nu_\mu\to\nu_e$ and $\overline{\nu}_\mu\to\overline{\nu}_e$ appearance probabilities.One of the dominant systematic uncertainties on the measurements of CP violation, comes from our modeling of the $\nu_e/\overline{\nu}_e$ cross-section ratio, which is subject to a range of uncertainties related to poorly-constrained nuclear physics processes.Whilst tight constraints on the $\nu_\mu/\overline{\nu}_\mu$ cross-section can be achieved using LBL experiment's near detector data, the lepton mass differences mean that the extrapolation to the $\nu_e/\overline{\nu}_e$ is not trivial.Currently running LBL experiments reach a sensitivity to exclude the CP conserving hypothesis of about three standard deviations for a relatively large range of $\delta_{CP}$ values, hence a more accurate evaluation of the $\nu_e/\overline{\nu}_e$ related uncertainties becomes increasingly crucial.Following up on work by Nikolakopoulos et al.~\cite{Nik}, we present the analysis from \cite{UncertaintiesOTDi}, quantifying the potential for miss-modelling of the $\nu_\mu/\nu_e, \ \overline{\nu}_\mu / \overline{\nu}_e$ and $\nu_e/\overline{\nu}_e$ cross sections due to nuclear effects as a model spread in the full kinematic phase space for CCQE interactions.This impact is then propagated to simulated experimental configurations based on the Hyper-K and ESS$\nu$SB experiments.Significant differences between the theoretical models are found, which largely lie in regions of phase space that contribute only a small portion of the flux integrated cross sections.Overall, a systematic uncertainty on the oscillated flux-averaged $\nu_e/\overline{\nu}_e$ cross section of $\sim 2$\% and $\sim4$\% is found for the simulated Hyper-K and ESS$\nu$SB experiments respectively..

Uncertainties on the $\nu_{\mu}$/$\nu_{e}$, $\bar{\nu}_{\mu}$/$\bar{\nu}_{e}$ and $\nu_{e}$/$\bar{\nu}_{e}$ cross-section ratio from the modelling of nuclear effects and their impact on neutrino oscillation experiments / Dieminger, T. (Zurich, ETH) ; Dolan, S. (CERN) ; Sgalaberna, D. (Zurich, ETH) ; Nikolakopoulos, A. (Fermilab) ; Dealtry, T. (Lancaster U.) ; Bolognesi, S. (IRFU, Saclay) ; Pickering, L. (Royal Holloway, U. of London) ; Rubbia, A. (Zurich, ETH)
The potential for mis-modeling of $\nu_{\mu}$/$\nu_{e}$, $\bar{\nu}_{\mu}$/$\bar{\nu}_{e}$ and $\nu_{e}$/$\bar{\nu}_{e}$ cross section ratios due to nuclear effects is quantified by considering model spread within the full kinematic phase space for CCQE interactions. Its impact is then propagated to simulated experimental configurations based on the Hyper-K and ESS$\nu$SB experiments. [...]

Measuring leptonic CP violation at the second neutrino oscillation maximum with ESSnuSB / Kliček , Budimir (speaker) (Rudjer Boskovic Institute)
ESSnuSB is a Design Study for an experiment which will measure CP violation in the lepton sector by observing neutrino oscillations at the second muon neutrino to electron neutrino oscillation maximum. The signal of CP violation at the second oscillation maximum is expected to be close three times larger than at the first one, which significantly increases the ratio between the signal and the systematic uncertainty, and thereby the physical reach of the project [...]

Higgs boson gluon-fusion production in N3LO QCD / Anastasiou, Charalampos (Zurich, ETH) ; Duhr, Claude (CERN ; Louvain U., CP3) ; Dulat, Falko (Zurich, ETH) ; Herzog, Franz (NIKHEF, Amsterdam) ; Mistlberger, Bernhard (Zurich, ETH)
We present the cross-section for the production of a Higgs boson at hadron-colliders at next-to- next-to-next-to-leading order (N3LO) in perturbative QCD. The calculation is based on a method to perform a series expansion of the partonic cross-section around the threshold limit to an arbitrary order. [...]
