Flipped Quartification and a composite -quark
James B. Dent, Thomas W. Kephart, Heinrich Päs +1
An alternative "flipped" version of the quartification model is obtained by rearrangement of the particle assignments. The model has two standard (trinification) families and one f…
The pros and cons of beyond standard model interpretations of ANITA events
L. A. Anchordoqui, I. Antoniadis, V. Barger +11
The Antarctic Impulsive Transient Antenna (ANITA) experiment has observed two air shower events with energy emerging from the Earth with exit angles $\sim 30^\…
The Migdal Effect and Photon Bremsstrahlung in effective field theories of dark matter direct detection and coherent elastic neutrino-nucleus scattering
Nicole F. Bell, James B. Dent, Jayden L. Newstead +2
Dark matter direct detection experiments have limited sensitivity to light dark matter (below a few GeV), due to the challenges of lowering energy thresholds for the detection of n…
Probing QCD approach to thermal equilibrium with ultrahigh energy cosmic rays
Jorge F. Soriano, Luis A. Anchordoqui, Thomas C. Paul +1
The Pierre Auger Collaboration has reported an excess in the number of muons of a few tens of percent over expectations computed using extrapolation of hadronic interaction models…
Sterile Neutrinos with Altered Dispersion Relations as an Explanation for Neutrino Anomalies
Dominik Döring, Heinrich Päs, Philipp Sicking +1
Recently the MiniBooNE Collaboration has confirmed its anomalous excess in (anti)muon- to (anti)electron-neutrino oscillation data. Combined with long-standing results from the LSN…
Upgoing ANITA events as evidence of the CPT symmetric universe
Luis A. Anchordoqui, Vernon Barger, John G. Learned +2
We explain the two upgoing ultra-high energy shower events observed by ANITA as arising from the decay in the Earth's interior of the quasi-stable dark matter candidate in the CPT…
Enhancing Dark Matter Annihilation Rates with Dark Bremsstrahlung
Nicole F. Bell, Yi Cai, James B. Dent +2
Many dark matter interaction types lead to annihilation processes which suffer from p-wave suppression or helicity suppression, rendering them subdominant to unsuppressed s-wave pr…
Strange fireball as an explanation of the muon excess in Auger data
Luis A. Anchordoqui, Haim Goldberg, Thomas J. Weiler
We argue that ultrahigh energy cosmic ray collisions in the Earth atmosphere can probe the strange quark density of the nucleon. These collisions have center-of-mass energies \agt…
Searching for New Heavy Neutral Gauge Bosons using Vector Boson Fusion Processes at the LHC
Florez Andres, Gurrola Alfredo, Johns Will +4
New massive resonances are predicted in many extensions to the Standard Model (SM) of particle physics and constitutes one of the most promising searches for new physics at the LHC…
Big Bang Nucleosynthesis in the presence of sterile neutrinos with altered dispersion relations
Elke Aeikens, Heinrich Päs, Sandip Pakvasa +1
Big Bang Nucleosynthesis imposes stringent bounds on light sterile neutrinos mixing with the active flavors. Here we discuss how altered dispersion relations can weaken such bounds…
IceCube neutrinos, decaying dark matter, and the Hubble constant
Luis A. Anchordoqui, Vernon Barger, Haim Goldberg +4
Cosmological parameters deduced from the Planck measurements of anisotropies in the cosmic microwave background are at some tension with direct astronomical measurements of various…
Majorana dark matter through the Higgs portal under the vacuum stability lamppost
Luis A. Anchordoqui, Vernon Barger, Haim Goldberg +4
We study the vacuum stability of a minimal Higgs portal model in which the standard model (SM) particle spectrum is extended to include one complex scalar field and one Dirac fermi…
Dark matter at the LHC: EFTs and gauge invariance
Nicole F. Bell, Yi Cai, James B. Dent +2
Effective field theory (EFT) formulations of dark matter interactions have proven to be a convenient and popular way to quantify LHC bounds on dark matter. However, some of the non…
New physics with ultra-high-energy neutrinos
D. Marfatia, D. W. McKay, T. J. Weiler
Now that PeV neutrinos have been discovered by IceCube, we optimistically entertain the possibility that neutrinos with energy above 100 PeV exist. We evaluate the dependence of ev…
Aspects of the Flavor Triangle for Cosmic Neutrino Propagation
Lingjun Fu, Chiu Man Ho, Thomas J. Weiler
Over cosmic distances, astrophysical neutrino oscillations average out to a classical flavor propagation matrix . Thus, flavor ratios injected at the cosmic source $W_…
Evidence for a Constant `Edge' in Proton-Proton Scattering at Very High Energies
Martin M. Block, Loyal Durand, Francis Halzen +2
Accurate fits to and cross section data up to Tevatron energies, incorporating the constraints imposed by analyticity and unitarity, successfully predict the results…
End of the cosmic neutrino energy spectrum
L. A. Anchordoqui, V. Barger, H. Goldberg +5
There may be a high-energy cutoff of neutrino events in IceCube data. In particular, IceCube does not observe either continuum events above 2 PeV, or the Standard Model Glashow-res…
Weinberg's Higgs portal confronting recent LUX and LHC results together with upper limits on B^+ and K^+ decay into invisibles
Luis A. Anchordoqui, Peter B. Denton, Haim Goldberg +4
We discuss a number of experimental constraints on Weinberg's Higgs portal model. In this framework, the standard model (SM) particle spectrum is extended to include one complex sc…
Using Integral Dispersion Relations to Extend the LHC Reach for New Physics
Peter B. Denton, Thomas J. Weiler
Many models of electroweak symmetry breaking predict new particles with masses at or just beyond LHC energies. Even if these particles are too massive to be produced on-shell at th…
Simple Mass Matrix Ansätze for Neutrino Mixing
HoSeong La, Thomas J. Weiler
We estimate the PMNS (Pontecorvo-Maki-Nakagawa-Sakata) matrix in terms of neutrino and charged lepton mixing given as $U_{\rm PMNS}=V_{\rm lep}^\dagger(\tildeθ_{13}) U_ν(\tildeθ_{2…

J. J. Beatty, A. E. Nelson, A. Olinto +62
Report of the CF6 Working Group at Snowmass 2013. Topics addressed include ultra-high energy cosmic rays, neutrinos, gamma rays, baryogenesis, and experiments probing the fundament…
Oscillation and Mixing Among the Three Neutrino Flavors
Thomas J Weiler
With the educated, interested non-specialist as the target audience, we overview what is known and not known about contemporary neutrino physics. Theory tells us that neutrinos are…
Likely Dominance of WIMP Annihilation to Fermion Pair + W/Z
Thomas J. Weiler
Arguably, the most popular candidate for Dark Matter (DM) is a massive, stable, Majorana fermion. However, annihilation of Majorana DM to two fermions features a helicity-suppresse…
