Factorization and resummation for single color-octet scalar production at the LHC
Ahmad Idilbi, Chul Kim, Thomas Mehen
Heavy colored scalar particles appear in a variety of new physics (NP) models and could be produced at the Large Hadron Collider (LHC). Knowing the total production cross section i…
Color Octet Scalar Bound States at the LHC
Chul Kim, Thomas Mehen
One possible extension of the Standard Model scalar sector includes SU(2)_L doublet scalars that are color octets rather than singlets. We focus on models in which the couplings to…
Hadronic Decays of the X(3872) to chi_{cJ} in Effective Field Theory
Sean Fleming, Thomas Mehen
The decays of the X(3872) to P-wave quarkonia are calculated under the assumption that it is a shallow bound state of neutral charmed mesons. The X(3872) is described using an effe…
On The Equivalence of Soft and Zero-Bin Subtractions
Thomas Mehen, Ahmad Idilbi
Zero-bin subtractions are required to avoid double counting soft contributions in collinear loop integrals in Soft-Collinear Effective Theory (SCET). In traditional approaches to f…
Implications of SU(2)_L x U(1) Symmetry for SIM(2) Invariant Neutrino Masses
Alan Dunn, Thomas Mehen
We consider SU(2)_L x U(1) gauge invariant generalizations of a nonlocal, Lorentz violating mass term for neutrinos that preserves a SIM(2) subgroup. This induces Lorentz violating…
