Multidimensional Included and Excluded Sums
Helen Xu, Sean Fraser, Charles E. Leiserson
This paper presents algorithms for the included-sums and excluded-sums problems used by scientific computing applications such as the fast multipole method. These problems are defi…
Left-Right Supersymmetry as the Origin of Flavor Physics
Sean Fraser, Emidio Gabrielli, Carlo Marzo +2
We propose a new framework for the observed flavor hierarchy and mixing based on left-right supersymmetry. The model contains the most minimal Higgs sector consisting only of gauge…
Towards a viable scalar interpretation of
Sean Fraser, Carlo Marzo, Luca Marzola +2
Recent measurements of semileptonic B-meson decays seemingly imply violations of lepton flavor universality beyond the Standard Model predictions. With three-level explanations bas…
The EDGES 21 cm Anomaly and Properties of Dark Matter
Sean Fraser, Andi Hektor, Gert Hütsi +8
The recently claimed anomaly in the measurement of the 21 cm hydrogen absorption signal by EDGES at , if cosmological, requires the existence of new physics. The possible…
Minimal flavor-changing models and muon after the measurement
Stefano Di Chiara, Andrew Fowlie, Sean Fraser +4
There has been a steady interest in flavor anomalies and their global fits as ideal probes of new physics. If the anomalies are real, one promising explanation is a new gauge…
Phenomenology of the Utilitarian Supersymmetric Standard Model
Sean Fraser, Corey Kownacki, Ernest Ma +3
We study the 2010 specific version of the 2002 proposed extension of the supersymmetric standard model, which has no term and conserves baryon number and lepton number…
Type II Radiative Seesaw Model of Neutrino Mass with Dark Matter
Sean Fraser, Corey Kownacki, Ernest Ma +1
We consider a model of neutrino mass with a scalar triplet assigned lepton number , so that the tree-level Yukawa coupling is not allowed. It…
Verifiable Associated Processes from Radiative Lepton Masses with Dark Matter
Sean Fraser, Ernest Ma, Mohammadreza Zakeri
If leptons do not couple directly to the one Higgs doublet of the standard model of particle interactions, they must still do so somehow indirectly to acquire mass, as proposed rec…
SU(2)_N Model of Vector Dark Matter with a Leptonic Connection
Sean Fraser, Ernest Ma, Mohammadreza Zakeri
Models of fermion and scalar dark matter abound. Here we consider instead vector dark matter, from an SU(2)_N extension of the standard model. It has a number of interesting proper…
Scotogenic Inverse Seesaw Model of Neutrino Mass
Sean Fraser, Ernest Ma, Oleg Popov
A variation of the original 2006 radiative seesaw model of neutrino mass through dark matter is shown to realize the notion of inverse seesaw naturally. The dark-matter candidate h…
Anomalous Higgs Yukawa Couplings
Sean Fraser, Ernest Ma
In the standard model, the Higgs boson couples to the quarks and charged leptons according to the well-known formula , where = quark (q) or lepton (l) and…
