Nonunitarity of the lepton mixing matrix at the European Spallation Source (2022)
Journal Article
Chatterjee, S. S., Miranda, O., Tórtola, M., & Valle, J. (2022). Nonunitarity of the lepton mixing matrix at the European Spallation Source. Physical Review D, 106(7), https://doi.org/10.1103/physrevd.106.075016

If neutrinos get mass through the exchange of lepton mediators, as in seesaw schemes, the neutrino appearance probabilities in oscillation experiments are modified due to effective nonunitarity of the lepton mixing matrix. This also leads to new CP p... Read More about Nonunitarity of the lepton mixing matrix at the European Spallation Source.

Impact of improved energy resolution on DUNE sensitivity to neutrino non-standard interactions (2021)
Journal Article
Chatterjee, S. S., Dev, P. B., & Machado, P. A. (2021). Impact of improved energy resolution on DUNE sensitivity to neutrino non-standard interactions. Journal of High Energy Physics, 2021(8), https://doi.org/10.1007/jhep08%282021%29163

The full physics potential of the next-generation Deep Underground Neutrino Experiment (DUNE) is still being explored. In particular, there have been some recent studies on the possibility of improving DUNE’s neutrino energy reconstruction. The main...

Nonstandard Neutrino Interactions as a Solution to the NOνA and T2K Discrepancy (2021)
Journal Article
Chatterjee, S. S., & Palazzo, A. (2021). Nonstandard Neutrino Interactions as a Solution to the NOνA and T2K Discrepancy. Physical Review Letters, 126(5), Article 051802. https://doi.org/10.1103/physrevlett.126.051802

The latest data of the two long-baseline accelerator experiments NOνA and T2K, interpreted in the standard three-flavor scenario, display a discrepancy. A mismatch in the determination of the standard CP phase δ CP extracted by the two experiments is... Read More about Nonstandard Neutrino Interactions as a Solution to the NOνA and T2K Discrepancy.

Enhancing sensitivity to non-standard neutrino interactions at INO combining muon and hadron information (2020)
Journal Article
Khatun, A., Chatterjee, S. S., Thakore, T., & Agarwalla, S. K. (2020). Enhancing sensitivity to non-standard neutrino interactions at INO combining muon and hadron information. The European Physical Journal C, 80(6), Article 533. https://doi.org/10.1140/epjc/s10052-020-8097-1

In this paper, we explore the impact of flavor violating neutral current non-standard interaction (NSI) parameter εμτ in the oscillation of atmospheric neutrinos and antineutrinos separately using the 50 kt magnetized ICAL detector at INO. We find th... Read More about Enhancing sensitivity to non-standard neutrino interactions at INO combining muon and hadron information.

Neutrino Mass Ordering Obscured by Nonstandard Interactions (2020)
Journal Article
Capozzi, F., Chatterjee, S. S., & Palazzo, A. (2020). Neutrino Mass Ordering Obscured by Nonstandard Interactions. Physical Review Letters, 124(11), Article 111801. https://doi.org/10.1103/physrevlett.124.111801

One of the major open questions in particle physics is the issue of the neutrino mass ordering (NMO). The current data of the two long-baseline experiments NOνA and T2K, interpreted in the standard threeflavor scenario, provide a ∼2.4σ indication in...

Physics potential of ESSνSB in the presence of a light sterile neutrino (2019)
Journal Article
Agarwalla, S. K., Chatterjee, S. S., & Palazzo, A. (2019). Physics potential of ESSνSB in the presence of a light sterile neutrino. Journal of High Energy Physics, 2019(12), Article 174. https://doi.org/10.1007/jhep12%282019%29174

ESSνSB is a proposed neutrino super-beam project at the ESS facility. We study the performance of this setup in the presence of a light eV-scale sterile neutrino, considering 540 km baseline with 2 years (8 years) of ν ( ν¯¯¯ ) run-plan. This baselin...
