Low-derivative operators of the Standard Model effective field theory via Hilbert series methods
Landon Lehman, Adam Martin
In this work, we explore an extension of Hilbert series techniques to count operators that include derivatives. For sufficiently low-derivative operators, we find an algorithm that…
Hilbert Series for Constructing Lagrangians: expanding the phenomenologist's toolbox
Landon Lehman, Adam Martin
This note presents the Hilbert series technique to a wider audience in the context of constructing group-invariant Lagrangians. This technique provides a fast way to calculate the…
Boosted Higgses from chromomagnetic 's: at high luminosity
Joseph Bramante, Antonio Delgado, Landon Lehman +1
This paper examines detection prospects and constraints on the chromomagnetic dipole operator for the bottom quark. This operator has a flavor, chirality and Lorentz structure that…
Extending the Standard Model Effective Field Theory with the Complete Set of Dimension-7 Operators
Landon Lehman
We present a complete list of the independent dimension-7 operators that are constructed using the Standard Model degrees of freedom and are invariant under the Standard Model gaug…
Clearing the Brush: The Last Stand of Solo Small Field Inflation
Joseph Bramante, Sean Downes, Landon Lehman +1
By incorporating both the tensor-to-scalar ratio and the measured value of the spectral index, we set a bound on solo small field inflation of .…
Surveying the Scope of the SU(2)_L Scalar Septet Sector
C. Alvarado, L. Lehman, B. Ostdiek
Extending the Standard Model by adding a scalar field transforming as a septet under preserves the parameter at tree level and can satisfy experimental constraints on…
