“…Systematic uncertainties will be relevant for such a large dataset, but a purely statistical rescaling of the present measurement would hint at the necessity of taking into account these subtle effects from interference. For example, Cepeda et al (2019) foresaw a precision on m h in the γγ channel of around 10-20 MeV (CMS Collaboration, 2022a, 2022b, thus calling for a careful evaluation of the interference effects.…”

“…By contrast, vector-portal dark matter coming from the π 0 decay through a dark photon is typically more energetic and hence deposits more energy into the detector. An energy cut rejects ν μ -induced events, leading to a dark-matter signal-rich region (deNiverville, Pospelov, and Ritz, 2015;Dutta et al, 2020Dutta et al, , 2022Aguilar-Arevalo et al, 2022a, 2022b). (c) The energy peak is useful in the energy distribution of cosmic photons from neutral pion decays.…”

“…However, owing to the scale of the beam energy, most of the produced neutrons are slowly moving, so their arrival timing at the detector is delayed compared to the pion-induced neutrino events. Therefore, restricting to the prompt region, one can efficiently reject beam-related neutrons; see Aguilar-Arevalo et al (2022a, 2022b]. (b) In a similar manner, neutrinos from muon decays can be vetoed using a timing cut in the stopped-pion neutrino experiments.…”

Kinematic variables play an important role in collider phenomenology, as they expedite discoveries of new particles by separating signal events from unwanted background events and allow for measurements of particle properties such as masses, couplings, and spins. For the past ten years, an enormous number of kinematic variables have been designed and proposed, primarily for the experiments at the CERN Large Hadron Collider, allowing for a drastic reduction of highdimensional experimental data to lower-dimensional observables, from which one can readily extract underlying features of phase space and develop better-optimized data-analysis strategies. Recent developments in the area of phase-space kinematics are reviewd, and new kinematic variables with important phenomenological implications and physics applications are summarized. Recently proposed analysis methods and techniques specifically designed to leverage new kinematic variables are also reviewed. As machine learning is currently percolating through many fields of particle physics, including collider phenomenology, the interconnection and mutual complementarity of kinematic variables and machine-learning techniques are discussed. Finally, the manner in which utilization of kinematic variables originally developed for colliders can be extended to other highenergy physics experiments, including neutrino experiments, is discussed.

Modern-day accelerator neutrino facilities are excellent venues for searches for new-physics particles. Many distinct new-physics models predict overlapping signatures and phenomenology in these experiments. In this work, we advocate for the adoption of simplified frameworks when studying these types of new-physics signatures, which are characterized by a small number of primary variables, including particle masses, lifetimes, and production and decay modes/rates that most directly control signal event rates and kinematics. In particular, taking the example of long-lived particles that decay inside a neutrino detector as a test case, we study formulate and study simplified frameworks in the context of light scalars/fermions produced in kaon decays which then decay into final states containing an electron-positron pair. We show that using these simplified frameworks can allow for individual experimental analyses to be applicable to a wide variety of specific model scenarios. As a side benefit, we demonstrate that using this approach can allow for the T2K collaboration, by reinterpreting its search for Heavy Neutral Leptons, to be capable of setting world-leading limits on the Higgs-Portal Scalar model. Furthermore, we argue the simplified framework interpretation can serve as a bridge to model identification in the hopeful detection of a new-physics signal. As an illustration, we perform a first determination of the likelihood that, in the presence of a new-physics signal in a detector like the DUNE ND-GAr, multiple different new-physics hypotheses (such as the Higgs-Portal Scalar and Heavy Neutral Lepton ones) can be disentangled. We demonstrate that this model discrimination is favorable for some portions of detectable new-physics parameter space but for others, it is more challenging.
