“…The ESSnuSB collaboration has proposed an upgrade of this facility, aiming to reduce the proton pulse length from 2.86 ms to 1.3 µs using a proton accumulator. This shortened pulse duration would enable the use of standard magnetic horns for beam focusing, effectively transforming the ESS into a Superbeam facility [59,60]. Operating at the second oscillation maximum, the facility aims to achieve superior sensitivity in detecting the CP violation phase δ.…”

Long-baseline neutrino experiments represent the optimal platforms for probing the lepton Yukawa sector of the Standard Model, and significant experiments are either under construction or in the planning stages. This review delves into the scientific motivations behind these facilities, which stem from the pivotal 2012 discovery of the θ13 mixing angle. We provide an overview of the two ongoing projects, DUNE and HyperKamiokande, detailing their physics potential and the technical hurdles they face. Furthermore, we briefly examine proposals for forthcoming endeavors and innovative concepts that could push beyond conventional Superbeam technology.

The ESSnuSB project aims to measure the leptonic CP violation at the second neutrino oscillation maximum using an intense neutrino beam, which will be produced by the powerful ESS proton linear accelerator. The first phase of the project was successfully concluded with the production of the Conceptual Design Report in which it was shown that this next-to-next generation neutrino oscillation experiment has a potential to start the precision era in the field of the leptonic CP violation measurement. ESSnuSB+ is a continuation of this study which focuses on neutrino interaction cross-section measurement at the low enutrino energy region, exploring the sensitivity of the experimental setup to additional physics scenarios and on the civil engineering of the near and far detectors sites. It foresees an intermediate step in the ESSnuSB construction phase in which a number of additional facilities will be built: a 1/4 power ESSnuSB neutrino production target system prototype, a low energy muon storage ring and a low energy monitored neutrino beam facility; a common near neutrino detector for the muon ring and monitored beam will be designed, and a study of the effect of Gd doping of ESSnuSB water Cherenkov detectors will be performed.

Study of nonstandard interactions mediated by a scalar field at the ESSnuSB experiment

In this paper, we study scalar mediator induced nonstandard interactions (SNSIs) in the context of the ESSnuSB experiment. In particular, we study the capability of ESSnuSB to put bounds on the SNSI parameters and also study the impact of SNSIs in the measurement of the leptonic CP phase δCP. Existence of SNSIs modifies the neutrino mass matrix and this modification can be expressed in terms of three diagonal real parameters (ηee, ημμ, and ηττ) and three off-diagonal complex parameters (ηeμ, ηeτ, and ημτ). Our study shows that the upper bounds on the parameters ημμ and ηττ depend upon how Δm312 is minimized in the theory. However, this is not the case when one tries to measure the impact of SNSIs on δCP. Further, we show that the CP sensitivity of ESSnuSB can be completely lost for certain values of ηee and ημτ for which the appearance channel probability becomes independent of δCP.
