The T2K experiment is a long baseline neutrino oscillation experiment.
One of the largest sources of uncertainty in neutrino oscillation experiments comes from our poor understanding of neutrino interaction cross-sections.
I will explain why this is the case, and summarise the work that is being done to improve on the current situation.

Cross-section measurements are extremely important for reducing systematic uncertainties in neutrino oscillation experiments, but are limited by our understanding of effects inside the target nucleus. Measuring neutrino interactions in gaseous detector allows the models used to simulate these effects to be empirically tested, thanks to the high spatial resolution of the detector and the...

To study the neutrino interaction with one proton at the final state we need to make a proton selection. I will present my latest results of my proton selection. It is a very interesting channel and help us understand the CP violation in the lepton sector. The theory is well understood but the analysis is challenging as the background is much greater than the signal.

We present the physics opportunities which can be explored with the Electromagnetic Calorimeters (ECals) of the Tokai-to-Kamioka (T2K) off-axis near detector (ND280). Due to the ECal's high mass, a large fraction of the neutrinos incident on ND280 interact within the constituent lead layers which form the ECal. This makes the ECal an excellent detector for use in making the world's first...

In 2014 the T2K experiment will reverse the polarity of the magnetic horns
and begin running with an anti-neutrino beam for the first time. Differences
in the oscillation probabilities between neutrinos and anti-neutrinos may provide
insight into charge-parity violation in the leptonic sector. In order to
measure the the anti-electron neutrino contamination in T2K's anti-muon...

Hyper-Kamiokande is a next generation underground water Cherenkov detector which will serve as far detector of a long-baseline neutrino experiment in Japan (the natural extension of the already successful T2K experiment).
The upgraded facilities at J-PARC will deliver an off-axis narrow band (~0.6 GeV) (anti-)neutrino beam (750kW~1MW) and direct it to Hyper-K that will measure the...

LAGUNA-LBNO (Large Appartus studying Grand Unification and Neutrino Astrophysics for Long Baseline Neutrino Oscillations) is a feasibility study with the intent to host next generation neutrino detectors. These experiments possess the ability to probe the universe further with proposed detectors of the 100 kton scale. A basic overview of the long baseline experiment is presented with the focus...

Analysis of the complete set of MINOS accelerator and atmospheric data, combining `$\nu_{\mu}$` disappearance and `$\nu_{e}$` appearance, was published in March 2014. This yielded precision measurements of `$\Delta m^{2}_{32}$` and `$sin^{2}(\theta_{23})$` as well as early constraints on `$\delta_{CP}$`. The first results from MINOS+, adding 2 years of atmospheric and 6 months of beam...

In arXiv: 1312.3871, we introduce a way to compute transition amplitudes in quantum field theory for scatterings between sources and detectors, that is scatterings over finite space-time domains. Our amplitudes are manifestly causal, by which we mean that the source and detector are always linked by a connected chain of retarded propagators. We illustrate how these amplitudes may be obtained...

I shall briefly review the main aspects of leptogenesis, describing both the unflavoured and the flavoured versions of the $N_2$-dominated scenario. A study of the success rates of both classes of models has been carried out and I will comment on that, as well as on the incidence of corrective effects to the simplest scenario. I will then focus on the flavoured case and consider the conditions...
