How Macroscopic Limits on Neutron Star Baryon Loss Yield Microscopic Limits on Non-Standard-Model Baryon Decay
Jeffrey M. Berryman, Susan Gardner, Mohammadreza Zakeri
We investigate how our baryon-loss limits from anomalous binary-pulsar period lengthening can be interpreted microscopically to yield specific constraints on the particle physics o…
Neutron Stars with Baryon Number Violation, Probing Dark Sectors
Jeffrey M. Berryman, Susan Gardner, Mohammadreza Zakeri
The neutron lifetime anomaly has been used to motivate the introduction of new physics with hidden-sector particles coupled to baryon number, and on which neutron stars provide pow…
Constraining Time Dependent Dark Matter Signals from the Sun
Mohammadreza Zakeri, Yu-Feng Zhou
Dark matter (DM) particles captured by the Sun can produce high energy electrons outside the Sun through annihilating into meta-stable mediators. The corresponding cosmic-ray elect…
Exotic Lepton-Flavor Violating Higgs Decays
Jared A. Evans, Philip Tanedo, Mohammadreza Zakeri
Exotic Higgs decays are promising channels to discover new physics in the near future. We present a simple model with a new light scalar that couples to the Standard Model through…
Non-Abelian Vector Boson as FIMP Dark Matter
Basabendu Barman, Subhaditya Bhattacharya, Mohammadreza Zakeri
In this analysis we demonstrate the freeze-in realization of a non-abelian vector boson dark matter (DM). We choose to elaborate an existing extension ( stands for neu…
Multipartite Dark Matter in extension of Standard Model and signatures at the LHC
Basabendu Barman, Subhaditya Bhattacharya, Mohammadreza Zakeri
An extension ( stands for neutral) of the Standard Model (SM) is proposed with an additional global symmetry, which stabilizes the lightest of the vector…
Alternative Model of Leptonic Color and Dark Matter
Corey Kownacki, Ernest Ma, Nicholas Pollard +2
The alternative model of leptonic color and dark matter is discussed. It unifies at GeV and has the low-energy subgroup $SU(3)_q \times SU(2)_l \time…
A Minimal Model For Two-Component FIMP Dark Matter: A Basic Search
S. Peyman Zakeri, S. Mohammad Moosavi Nejad, Mohammadreza Zakeri +1
In the multi-component configurations of dark matter phenomenology, we propose a minimal two-component configuration which is an extension of the Standard Model with only three new…
Dark Revelations of the and Gauge Extensions of the Standard Model
Corey Kownacki, Ernest Ma, Nicholas Pollard +2
Two theoretically well-motivated gauge extensions of the standard model are and , wher…
Dark Gauge U(1) Symmetry for an Alternative Left-Right Model
Corey Kownacki, Ernest Ma, Nicholas Pollard +2
An alternative left-right model of quarks and leptons, where the lepton doublet is replaced with so that is not the Dirac mass partner of ,…
Quartified Leptonic Color, Bound States, and Future Electron-Positron Collider
Corey Kownacki, Ernest Ma, Nicholas Pollard +2
The quartification model of Babu, Ma, and Willenbrock (BMW), proposed in 2003, predicts a confining leptonic color gauge symmetry, which becomes strong at the k…
Generalized Gauge U(1) Family Symmetry for Quarks and Leptons
Corey Kownacki, Ernest Ma, Nicholas Pollard +1
If the standard model of quarks and leptons is extended to include three singlet right-handed neutrinos, then the resulting fermion structure admits an infinite number of anomaly-f…
Gauge Model of Radiative Neutrino Mass with Multipartite Dark Matter
Ernest Ma, Nicholas Pollard, Oleg Popov +1
We propose an extension of the standard model of quarks and leptons to include gauge symmetry with an exotic array of neutral fermion singlets for anomaly cancellation. With…
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…
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…
Gauge Model with Residual Symmetry
Ernest Ma, Nicholas Pollard, Rahul Srivastava +1
We study a gauge extension of the standard model of quarks and leptons with unconventional charges for the singlet right-handed neutrinos, and extra singlet scalars, such tha…
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…
