“…At present, the strongest preference for one of the two possible orderings by a single experiment comes from Super-Kamiokande, which favors normal ordering at ∼ 1.4σ [41]. Results from long-baseline oscillation experiments such as NOνA [42] or T2K [43], instead, provide a preference for normal ordering around the 2σ level (each) only when a prior on θ 13 from reactor experiments is adopted. When all relevant neutrino oscillation experiments are combined in a global fit, the preference rises up to ∼ 3σ [10,12,13].…”

The PTOLEMY project aims to develop a scalable design for a Cosmic Neutrino Background (CNB) detector, the first of its kind and the only one conceived that can look directly at the image of the Universe encoded in neutrino background produced in the first second after the Big Bang. The scope of the work for the next three years is to complete the conceptual design of this detector and to validate with direct measurements that the nonneutrino backgrounds are below the expected cosmological signal. In this paper we discuss in details the theoretical aspects of the experiment and its physics goals. In particular, we mainly address three issues. First we discuss the sensitivity of PTOLEMY to the standard neutrino mass scale. We then study the perspectives of the experiment to detect the CNB via neutrino capture on tritium as a function of the neutrino mass scale and the energy resolution of the apparatus. Finally, we consider an extra sterile neutrino with mass in the eV range, coupled to the active states via oscillations, which has been advocated in view of neutrino oscillation anomalies. This extra state would contribute to the tritium decay spectrum, and its properties, mass and mixing angle, could be studied by analyzing the features in the beta decay electron spectrum.

“…There are two stable nitrogen isotopes, 14 N and 15 N, and their relative abundances are expressed as δ 15 N values -the parts per thousand deviation of the 15 N/ 14 N ratio from a standard value. The nitrogen isotopic compositions of mantle-derived samples can provide insight into a wide range of topics, from the mix of planetary building blocks that brought volatile species to Earth during its formation 2 , to the transport of atmospheric nitrogen into the mantle through the sinking of tectonic plates over time 3 .…”

“…Since their discovery, neutrino oscillations have been analysed in several experiments, but only in the past few years have tiny oscillations from muon neutrinos to electron neutrinos been observed 13,14 . The probability of this oscillation occurring is small, but it holds the key to leptonic CP violation: if CP symmetry is conserved, the oscillation…”

We present a comprehensive analysis in the 3+1 active-sterile neutrino oscillation scenario for the sensitivity of the ESSnuSB experiment in the presence of light sterile neutrinos assuming both a far (FD) and a near (ND) detector. Our analysis show that when the ND is included, the results are significantly different compared to the ones obtained with the FD only. We find that the capability of ESSnuSB to constrain the sterile mixing parameters is sin 2 2θ µe ∼ 10 −4 for ∆m 2 = 1 eV 2 if the ND is included and it becomes sin 2 2θ µe ∼ 10 −2 without the ND. Furthermore, we show that the sensitivity can go down to sin 2 2θ µe ∼ 10 −3 for the most conservative choice of the systematics on the ND. Comparing the sensitivity with T2HK, T2HKK, and DUNE by considering the FD only, we find that the sensitivity of ESSnuSB is smaller for most of the parameter space. Studying the CP violation sensitivity, we find that if the ND is included, it can be larger in the 3+1 scenario than in the standard one. However, if the ND is not included, the sensitivity is smaller compared to the one in the standard scenario. We also find that the CP violation sensitivity due to δ 13 is larger compared to the one induced by δ 24 . The sensitivities are slightly better for the dominant neutrino running ratio of ESSnuSB.
