The CROSS experiment: detector construction, background projection, and sensitivity to Mo decay
D. Auguste, A. S. Barabash, G. Benato +42
The paper describes the construction of the CROSS cryogenic scintillating calorimeter array for searching neutrinoless double‑beta decay of ^100Mo, and presents Monte‑Carlo backgro…
A HEFT Perspective on the Type-II Seesaw Model and the Complete Basis of Lepton-Number-Violating Operators
Zizhou Ge, Huayang Song, Xia Wan
The paper performs a complete tree‑level matching of the type‑II seesaw model onto the Higgs Effective Field Theory (HEFT) up to order p⁴, and builds a non‑redundant basis of lepto…
Intrinsic Spatial Position Resolution of P-type Point-Contact Germanium Detector
R. M. J. Li, S. K. Liu, S. T. Lin +8
The paper presents a method to quantify the intrinsic spatial position resolution of p-type point‑contact germanium detectors using optimized cross‑scanning and pulse‑shape analysi…
Impact of dim-6 SMEFT operators on low-scale leptogenesis
Kaori Fuyuto, Julia Harz, Sascha Weber
The paper studies how a dimension‑six lepton‑number‑conserving operator in the neutrino‑extended SMEFT modifies the production and equilibration of right‑handed neutrinos in low‑sc…
Challenging Majorana neutrino effects in and decays
Asmaa Abada, Claire Chevallier, Luighi P. S. Leal +3
The paper examines how lepton-number-violating effective operators influence the rare decays B→K^{(*)}νν and K→πνν, showing that standard SMEFT operators are tightly constrained by…
