Vector boson fusion processes become increasingly more important at higher collider energies and for probing larger mass scales due to collinear logarithmic enhancements of the cross section. In this context, we revisit the production of a hypothetic heavy Majorana neutrino (N ) at hadron colliders. Particular attention is paid to the fusion process W γ → N ℓ ± . We systematically categorize the contributions from a photon initial state in the elastic, inelastic, and deeply inelastic channels. Comparing with the leading channel via the Drell-Yan production qq ′ → W * → N ℓ ± at NNLO in QCD, we find that the W γ fusion process becomes relatively more important at higher scales, surpassing the DY mechanism at m N ∼ 1 TeV (770 GeV), at the 14 TeV LHC (100 TeV VLHC). We investigate the inclusive heavy Majorana neutrino signal, including QCD corrections, and quantify the Standard Model backgrounds at future hadron colliders. We conclude that, with the currently allowed mixing |V µN | 2 < 6 × 10 −3 , a 5σ discovery can be made via the same-sign dimuon channel for m N = 530 (1070) GeV at the 14 TeV LHC (100 TeV VLHC) after 1 ab −1 . Reversely, for m N = 500 GeV and the same integrated luminosity, a mixing |V µN | 2 of the order 1.1 × 10 −3 (2.5 × 10 −4 ) may be probed.

The aim of the study was to determine the aquifer potential of lithostratigraphic units in Agocucho, Cajamarca, using the vertical electric sounding method (SEV). The SEV was applied using the Schlumberger configuration to determine the resistivity and delineate the aquifer that will allow the extraction of groundwater in the wells. SEV 7 was carried out in the study area, the data obtained were analyzed using the IPI2WIN software where 3 geoelectric layers were identified. The potential of the aquifer is in geoelectric layer 2 with a resistivity of 216 Ω.m to 302.83 Ω.m at surface depths between 25m to 85m, correlating it with local geology as alluvial deposits.
