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…

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…
