abstract
We present the GLoBES (``General Long Baseline Experiment Simulator'') software package, which allows the simulation of long-baseline and reactor neutrino oscillation experiments. One part of the software is the abstract experiment definition language to define experiments with beam and full detector descriptions as accurate as possible. Many systematics options are provided, such as normalization and energy calibration errors, or the choice between spectral or total rate information. For the definition of experiments, a new transparent building block concept is introduced. In addition, an additional program provides the possibility to develop and test new experiment definitions quickly. Another part of GLoBES is the user's interface, which provides probability, rate, and $\Delta \chi^2$ information for a given experiment or any combination of up to 32 experiments in C. Especially, the $\Delta \chi^2$ functions allow a simulation with statistics only, systematics, correlations, and degeneracies. In particular, GLoBES can handle the full multi-parameter correlation among the oscillation parameters, external input, and matter density uncertainties.

A sterile neutrino with a novel density-dependent matter potential Vs resolves multiple oscillation anomalies when Vs is negative and mixing angles are small.
Combined CPT-violating and CPT-conserving Lorentz-invariance-violation parameters suppress DUNE's CP-violation sensitivity below 3σ over much of the δ_CP range and introduce parameter degeneracies that complicate δ_CP extraction.
T2K and NOνA extract only a small fraction of the quantum information about δ_CP, with extraction efficiency particularly suppressed near maximal CP violation.
A new correlation-exploiting parameter is introduced for dual-baseline neutrino oscillation experiments to aid determination of mass hierarchy and CP phase, analyzed in the T2HKK context.
PRISM multi-angle measurements in DUNE restore sensitivity to non-unitarity and sterile neutrinos in electron and muon sectors to levels achievable with small spectral uncertainties, with only marginal gains for tau neutrinos.
GLoBES simulations show that DUNE can probe quasi-Dirac sterile-neutrino mixing down to θ_sa ≈ 0.05 with uniform coverage, while current NOvA+T2K data constrains θ_sa ≳ 0.08.
Feasibility projections indicate that an optimized NINJA-like detector at the SS floor location can deliver competitive constraints on active-sterile mixing parameters for eV-scale mass-squared differences.
First JUNO data yields competitive bounds on decoherence and invisible decay parameters in neutrino oscillations while preserving standard oscillation measurements.
T2K and NOvA data exclude dark-dimension neutrino models with bulk mass |c| < ~0.1 eV for a 10 µm extra dimension.
With 5.4 Mt·year atmospheric neutrino exposure, ESSnuSB could constrain |ε_eμ^m| < 0.053, |ε_eτ^m| < 0.057, |ε_μτ^m| < 0.021 and related diagonal differences at 90% CL, while NSI would alter mass ordering and θ23 octant sensitivities.
Model-agnostic treatment of neutrino cross-section ratios degrades CP-violation sensitivity in DUNE and T2HK by 3-4σ, but prospective νSCOPE data restores most of it.
ESSnuSB far detector shows varying event rates across supernova models and potential to distinguish them depending on distance, systematics, and efficiency.
Simulations show that tau neutrino appearance at DUNE improves sensitivity to NSI parameters especially ε_μτ, hierarchy, CP violation, octant, NSI phases, and PMNS unitarity constraints.
Analysis of recent NOνA and T2K data under non-unitary mixing yields tighter 90% limits on non-unitary parameters than prior data and indicates that α10 could reduce the 1σ tension between experiments for normal hierarchy.
Updated global fit of neutrino oscillation data gives precise measurements of mixing parameters with a 2.5 sigma preference for normal mass ordering.
