“…While the background estimation for 30 MeV line is complex, the target region is also subject to intense analysis efforts for diffuse supernova neutrino searches [37]. Far easier is the background estimation for the 236 MeV line, which is dominated by the atmospheric neutrino background [38]. We will thus only calculate the sensitivities of WC detectors to the monoenergetic neutrino from kaon decay.…”

Dark matter can be gravitationally captured by the Sun after scattering off solar nuclei. Annihilations of the dark matter trapped and accumulated in the centre of the Sun could result in one of the most detectable and recognizable signals for dark matter. Searches for high-energy neutrinos produced in the decay of annihilation products have yielded extremely competitive constraints on the spin-dependent scattering cross sections of dark matter with nuclei. Recently, the low energy neutrino signal arising from dark-matter annihilation to quarks which then hadronize and shower has been suggested as a competitive and complementary search strategy. These high-multiplicity hadronic showers give rise to a large amount of pions which will come to rest in the Sun and decay, leading to a unique sub-GeV neutrino signal. We here improve on previous works by considering the monoenergetic neutrino signal arising from both pion and kaon decay. We consider searches at liquid scintillation, liquid argon, and water Cherenkov detectors and find very competitive sensitivities for few-GeV dark matter masses.

“…As we review below, proton decay in the minimal supersymmetric SU (5) GUT is predominantly induced by the dimension-five effective operators [26] generated by colortriplet Higgs exchange. In this case, the most important decay mode is generally p → K + ν, for which the current lower decay lifetime limit is 6.6 × 10 33 yr [5,6]. 1 In the models we study, the decay n → K 0 ν is expected to occur at a similar rate, as these two decay channels are related through an SU(2) isospin rotation.…”

“…As reviewed in [4] and discussed in more detail in Section 2, the JUNO experiment is expected to have 90% CL sensitivity to the p → K + ν decay mode at the level of a lifetime > 2 × 10 34 yr after operating for 10 years-see Section 10 of [1], the DUNE experiment is expected to have 90% CL exclusion sensitivity to p → K + ν at the level of ∼ 6.5×10 34 yr after 20 years-see Chapter 4 of Volume 2 of the DUNE CDR [2], and the Hyper-Kamiokande (Hyper-K) experiment is expected to have 90% CL exclusion sensitivity to p → K + ν at the level of ∼ 5 × 10 34 yr after 20 years-see Section III.2 of the Hyper-Kamiokande TDR [3]. These sensitivities reach around an order of magnitude better than the current experimental limit [5,6].…”

Encouraged by the advent of a new generation of underground detectors-JUNO, DUNE and Hyper-Kamiokande-that are projected to improve significantly on the present sensitivities to various baryon decay modes, we revisit baryon decay in the minimal supersymmetric SU(5) GUT. We discuss the phenomenological uncertainties associated with hadronic matrix elements and the value of the strong coupling α s -which are the most important-the weak mixing angle θ W , quark masses including one-loop renormalization effects, quark mixing and novel GUT phases that are not visible in electroweak interaction processes. We apply our analysis to a variety of CMSSM, super-and sub-GUT scenarios in which soft supersymmetry-breaking parameters are assumed to be universal at, above and below the GUT scale, respectively. In many cases, we find that the next generation of underground detectors should be able to probe models with sparticle masses that are O(10) TeV, beyond the reach of the LHC. December 2019arXiv:1912.04888v1 [hep-ph] 10 Dec 2019 1 A preliminary update to the limit on this decay channel is reported in [27]: τ (p → K + ν) > 8.2 × 10 33 yr.2 There is a short discussion of p → e + π 0 in the Appendix. 3 A recent update of this limit is reported in Ref. [27]: τ (p → e + π 0 ) > 2.0 × 10 34 yr. 4 A preliminary update, τ (p → µ + π 0 ) > 1.2 × 10 34 yr, is given in Ref. [27].

Using light-cone sum rule techniques, we estimate the form factors which parametrise the hadronic matrix elements that are relevant for semi-leptonic three-body proton decays. The obtained form factors allow us to determine the differential rate for the decay of a proton (p) into a positron (e+), a neutral pion (π0) and a graviton (G), which is the leading proton decay channel in the effective theory of gravitons and Standard Model particles (GRSMEFT). The sensitivity of existing and next-generation neutrino experiments in detecting the p → e+π0G signature is studied and the phenomenological implications of our computations for constraints on the effective mass scale that suppresses the relevant baryon-number violating GRSMEFT operator are discussed.
