We present results on the reconstruction of electromagnetic (EM) activity from photons produced in charged current $ u_{mu}$ interactions with final state $pi^0$s. We employ a fully-automated reconstruction chain capable of identifying EM showers of $mathcal{O}$(100) MeV energy, relying on a combination of traditional reconstruction techniques together with novel machine-learning approaches. These studies demonstrate good energy resolution, and good agreement between data and simulation, relying on the reconstructed invariant $pi^0$ mass and other photon distributions for validation. The reconstruction techniques developed are applied to a selection of $ u_{mu} + {rm Ar} rightarrow mu + pi^0 + X$ candidate events to demonstrate the potential for calorimetric separation of photons from electrons and reconstruction of $pi^0$ kinematics.
The ArgoNeuT collaboration reports the first measurement of neutral current $pi^{0}$ production in $ u_{mu}$-argon and $bar{ u}_{mu}$-argon scattering. This measurement was performed using the ArgoNeuT liquid argon time projection chamber deployed at
We report the first measurement of the flux-integrated cross section of $ u_{mu}$ charged-current single $pi^{0}$ production on argon. This measurement is performed with the MicroBooNE detector, an 85 ton active mass liquid argon time projection cham
Time-integrated $CP$ asymmetries in $D^0$ decays to the final states $K^- K^+$ and $pi^- pi^+$ are measured using proton-proton collisions corresponding to $3mathrm{,fb}^{-1}$ of integrated luminosity collected at centre-of-mass energies of $7mathrm{
A search for CP violation in $D^0 rightarrow K^{-} K^{+} $ and $D^0 rightarrow pi^{-} pi^{+} $ decays is performed using $pp$ collision data, corresponding to an integrated luminosity of $3~fb^{-1}$, collected using the LHCb detector at centre-of-mas
