“…This limit has been obtained in [6] by considering the same signal region for p → e + π 0 as the latest SK search [47]. Consequently, we can again use (6.10), (6.14) and (6.17 This bound on the Wilson coefficient of the dimension-eight baryon-number violating operator (2.1) is probably the ultimate limit that can be set with next-generation neutrino detectors, because both JUNO and DUNE are not expected to reach the HK sensitivity to the p → e + π 0 mode cf.…”

“…We have then derived bounds on the amount of dimension-eight baryon-number violation in the GRSMEFT considering both the inclusive search for p → e + X [3,48] and the exclusive search for p → e + π 0 . It turns out that the best constraint arises at the moment from the latest SK search for the two-body decay JHEP11(2021)144 mode p → e + π 0 [47]. In fact, this search is able to set a 90% CL lower limit of 185 GeV on the effective mass scale that suppresses the relevant baryon-number violating GRSMEFT interactions.…”

“…In the rest frame of the proton these quantities can be expressed in terms of the graviton energy as m eπ = m p (m p − 2E G ) and p eπ = E G . In the latest SK search [47] the definition of the signal region involves the requirements m eπ > 800 MeV and p eπ < 250 MeV, meaning that all p → e + π 0 G events that satisfy the m eπ selection also pass the p eπ cut. To quantify by how much a lower cut m eπ > m cut eπ reduces the observed p → e + π 0 G rate we introduce the acceptance…”

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.

Employing nucleon decay as a fingerprint of SUSY GUT models using SusyTCProton

While the observation of nucleon decay would be a smoking gun of Grand Unified Theories (GUTs) in general, the ratios between the decay rates of the various channels carry rich information about the specific GUT model realization. To investigate this fingerprint of GUT models in the context of supersymmetric (SUSY) GUTs, we present the software tool SusyTCProton, which is an extension of the module SusyTC to be used with the REAP package. It allows to calculate nucleon decay rates from the relevant dimension five GUT operators specified at the GUT scale, including the full loop-dressing at the SUSY scale. As an application, we investigate the fingerprints of two example GUT toy models with different flavor structures, performing an MCMC analysis to include the experimental uncertainties for the charged fermion masses and CKM mixing parameters. While both toy models provide equally good fits to the low energy data, we show how they could be distinguished via their predictions of ratios for nucleon decay rates. Together with SusyTCProton we also make the additional module ProtonDecay public. It can be used independently from REAP and allows to calculate nucleon decay rates from given D = 5 and D = 6 operator coefficients (accepting the required SUSY input for the D = 5 case in SLHA format). The D = 6 functionality can also be used to calculate nucleon decay in non-SUSY GUTs.
