Missing Scalars at the Cosmological Collider
Qianshu Lu, Matthew Reece, Zhong-Zhi Xianyu
Light scalar fields typically develop spatially varying backgrounds during inflation. Very often they do not directly affect the density perturbations, but interact with other fiel…
Supersymmetric Alignment Models for
Yuichiro Nakai, Matthew Reece, Motoo Suzuki
Hierarchical masses of quarks and leptons are addressed by imposing horizontal symmetries. In supersymmetric Standard Models, the same symmetries play a role in suppressing flavor…
Axion Mass from Magnetic Monopole Loops
JiJi Fan, Katherine Fraser, Matthew Reece +1
We show that axions interacting with abelian gauge fields obtain a potential from loops of magnetic monopoles. This is a consequence of the Witten effect: the axion field causes th…
Challenges for an axion explanation of the muon measurement
Manuel A. Buen-Abad, JiJi Fan, Matthew Reece +1
The discrepancy between the muon measurement and the Standard Model prediction points to new physics around or below the weak scale. It is tantalizing to consider the loop ef…
Spontaneous CP Violation and Horizontal Symmetry in the MSSM: Toward Lepton Flavor Naturalness
Daniel Aloni, Pouya Asadi, Yuichiro Nakai +2
We study the contributions of supersymmetric models with a horizontal symmetry and only spontaneous CP breaking to various lepton flavor observables, such as and t…
