Measurement of single charged pion production in charged-current $ν_μ$-Ar interactions with the MicroBooNE detector
We present flux-averaged charged-current $ν_μ$ cross-section measurements on argon for final states containing exactly one $π^\pm$ and no other hadrons except nucleons. The analysis uses data from the MicroBooNE experiment in the Booster Neutrino Beam, corresponding to $1.11 \times 10^{21}$ protons on target. Total and single-differential cross-section measurements are provided within a phase space restricted to muon momenta above 150 MeV, pion momenta above 100 MeV, and muon-pion opening an…

Interacting Barrow holographic dark energy model in the presence of radiation and matter
We have studied the effect of radiation in the interacting barrow holographic dark energy model for a non-flat universe. For both open and closed universes, we have obtained the evolution equation for the density parameters for dark energy, dark matter and radiation for a specific kind of interaction among the seven possible linear interactions; the analysis with the remaining six interactions will be updated soon in this manuscript. We have then numerically solved those coupled differential eq…

Testing T2K's Bayesian constraints with priors in alternate parameterisations
Bayesian analysis results require a choice of prior distribution. In long-baseline neutrino oscillation physics, the usual parameterisation of the mixing matrix induces a prior that privileges certain neutrino mass and flavour state symmetries. Here we study the effect of privileging alternate symmetries on the results of the T2K experiment. We find that constraints on the level of CP violation (as given by the Jarlskog invariant) are robust under the choices of prior considered in the analysis…

Wonderful #biochar making workshop yesterday at Bellingen Northbank Community Gardens. After all our worry about the ECL that is forming, the weather ended up being perfect. Booked out and then extras so it was a big and enthusiastic group with an inspiring range of applications for it and lots we leaned from them. We emptied the cooled down demo barrel this morning and there was a nice barrow …

The Barrow entropies in the thermodynamics of high-dimensional Gauss-Bonnet black holes
We study the thermodynamics of $D$-dimensional Gauss-Bonnet black holes with Barrow entropy. It is found that the Gauss-Bonnet coupling and the Barrow factor revise the thermodynamic variables such as event horizon, Hawking temperature, entropy and heat capacity. It is interesting that the larger five-dimensional black holes exist stably and the smaller ones evaporate to disappear owing to the nature of heat capacities amended by the coupling and factor. The discussions exhibit that the $D$-dim…

Measurement of charged-current muon neutrino-argon interactions without pions in the final state using the MicroBooNE detector
We report a new measurement of flux-integrated differential cross sections for charged-current (CC) muon neutrino interactions with argon nuclei that produce no final state pions $(ν_μ\mathrm{CC}0π)$. These interactions are of particular importance as a topologically defined signal dominated by quasielastic-like interactions. This measurement was performed with the MicroBooNE liquid argon time projection chamber detector located at the Fermilab Booster Neutrino Beam (BNB), and uses an exposu…

Holographic dark energy models in $f(Q,T)$ gravity and cosmic constraint
In this work, we propose a new model that combines holographic dark energy with modified gravity $f(Q,T)$ to explore a possible explanation for the accelerated expansion of the universe. We incorporate the holographic principle into non-metric gravity with non-minimal matter coupling and introduce the Barrow holographic dark energy model to account for a tighter corrections, allowing for a more generalized discussion. Furthermore, we perform parameter estimation using the latest observational d…

Readout electronics for low occupancy High-Pressure Gas TPCs
HPgTPCs have benefits such as low energy threshold, magnetisability, and 4$π$ acceptance, making them ideal for neutrino experiments such as DUNE. We present the design of an FPGA-based solution optimised for ND-GAr, which is part of the Phase-II more capable near detector for DUNE. These electronics reduce the cost significantly compared to using collider readout electronics which are typically designed for much higher occupancy and therefore, for example, need much larger numbers of FPGAs an…

Introducing a Markov Chain-Based Time Calibration Procedure for Multi-Channel Particle Detectors: Application to the SuperFGD and ToF Detectors of the T2K Experiment
Inter-channel mis-synchronisation can be a limiting factor to the time resolution of high performance timing detectors with multiple readout channels and independent electronics units. In these systems, time calibration methods employed must be able to efficiently correct for minimal mis-synchronisation between channels and achieve the best detector performance. We present an iterative time calibration method based on Markov Chains, suitable for detector systems with multiple readout channels. …

York's Cavity Formalism and Quantum Modified Thermodynamics of (2+1)D Black Holes
We investigate the thermodynamic behavior of $(2+1)$ dimensional BTZ black holes using York's cavity formalism, in which the black hole is enclosed within a finite-radius boundary held at a fixed temperature. This canonical ensemble construction enables the precise derivation of thermodynamic quantities such as temperature, energy, entropy, pressure, and heat capacity via the integral Euclidean path approach. Extending this analysis, we incorporate quantum corrections through Barrow entropy, a …

Results from the T2K experiment on neutrino mixing including a new far detector $μ$-like sample
T2K has made improved measurements of three-flavor neutrino mixing with 19.7(16.3)$\times 10^{20}$ protons on target in (anti-)neutrino-enhanced beam modes. A new sample of muon-neutrino events with tagged pions has been added at the far detector, increasing the neutrino-enhanced muon-neutrino sample size by 42.5%. In addition, new samples have been added at the near detector, and significant improvements have been made to the flux and neutrino interaction modeling. T2K data continues to prefer…
