How to Identify a Majoron: Effective Field Theories of Spontaneous Lepton Number Breaking
Carla Biggio, Marta Fuentes Zamoro, Xu Li +2
We revisit the traditional type~I, II, and III seesaw mechanisms in the presence of a complex scalar field charged under a global symmetry that can be identified with lepton…
Isolating chirality-breaking SMEFT operators with Drell-Yan angular analysis
Samuele Grossi, Xu Li, Lorenzo Rolla +1
We present a comprehensive strategy to isolate the effect of a class of chirality-breaking interactions in the Standard Model Effective Field Theory (SMEFT) by exploiting Drell-Yan…
Lam-Tung relation breaking effects and weak dipole moments at lepton colliders
Guanghui Li, Xu Li, Bin Yan
The breaking of the Lam-Tung relation in the Drell-Yan process at the LHC exhibits a long-standing tension with the Standard Model (SM) prediction at accuracy.…
Lam-Tung relation breaking in boson production as a probe of SMEFT effects
Xu Li, Bin Yan, C. -P. Yuan
The violation of Lam-Tung relation in the high- region of the Drell-Yan process at the LHC presents a long-standing discrepancy with the standard model prediction a…
Positivity restrictions on the mixing of dimension-eight SMEFT operators
Mikael Chala, Xu Li
We discuss the structure of the mixing among dimension-eight operators in the SMEFT relying on the positivity of two-to-two forward scattering amplitudes. We uncover tens of new no…
