# Sensitivity study of Protvino to ORCA (P2O) experiment: Effect of antineutrino run, background and systematics

## TL;DR

This paper evaluates the P2O experiment's potential to study neutrino oscillations by analyzing the effects of antineutrino runs, background, and systematic uncertainties on its sensitivity.

## Contribution

It provides a comprehensive sensitivity analysis of the P2O experiment, highlighting the impact of antineutrino runs, background, and systematics on neutrino oscillation measurements.

## Key findings

- Antineutrino runs improve sensitivity to oscillation parameters.
- Background levels significantly affect measurement precision.
- Controlling systematics enhances overall experiment sensitivity.

## Abstract

There is a proposal to send a neutrino beam from the Protvino accelerator complex located in Russia to the detector facility called `Oscillation Research with Cosmics in the Abyss' (ORCA) in the Mediterranean sea to study neutrino oscillation. This is called the P2O experiment which will have a baseline of 2588 km. In this paper, we carry out a sensitivity study to extract the best possible physics sensitivity of the P2O experiment. In particular, we study the effect of antineutrino runs, the role of background as well as the impact of controlling the systematic uncertainties vis-a-vis the statistics.
