Multiple Axions Save High-Scale Inflation
Dan Kondo, Hitoshi Murayama
Many models of dark matter QCD axion requires inflation at a scale ~GeV and hence does not allow for a detectable tensor mode fluctuation. This is b…
Near-SUSY to Non-SUSY Crossover
Dan Kondo, Hitoshi Murayama, Bea Noether
Gauge theories can be solved exactly slightly away from the supersymmetric (SUSY) limit softly broken by anomaly mediation when the size of SUSY breaking is much smaller than the d…
Axion dark matter detection via shift current
Dan Kondo, Takahiro Morimoto, Genta Osaki +1
We propose a novel method to detect axion dark matter based on a topological phenomenon known as the shift current. We make use of the second-order nonlinearity of the shift curren…
Phase transition on superfluid vortices in Higgs-Confinement crossover
Tomoya Hayata, Yoshimasa Hidaka, Dan Kondo
We propose a novel method to distinguish states of matter by identifying spontaneous symmetry breaking on extended objects, such as vortices, even in the absence of a bulk phase tr…
LHC EFT WG Note: Basis for Anomalous Quartic Gauge Couplings
Gauthier Durieux, Grant N. Remmen, Nicholas L. Rodd +5
In this note, we give a definitive basis for the dimension-eight operators leading to quartic -- but no cubic -- interactions among electroweak gauge bosons. These are often called…
Exploration to early universe by Josephson Junction Switching Current Detector
Dan Kondo
In this paper, we propose a method to probe a Stochastic Gravitational Wave Background (SGWB) with Josephson Junction Switching Current Detector (JJSCD). The sensitivity for the sh…
Axion detection via superfluid He ferromagnetic phase and quantum measurement techniques
So Chigusa, Dan Kondo, Hitoshi Murayama +2
We propose to use the nuclear spin excitation in the ferromagnetic A1 phase of the superfluid He for the axion dark matter detection. This approach is striking in that it is se…
23, 381, 6242, 103268, 1743183, ...: Hilbert series for CP-violating operators in SMEFT
Dan Kondo, Hitoshi Murayama, Risshin Okabe
We introduce a systematic method to classify the Standard Model Effective Field Theory (SMEFT) operators based on their CP properties with the Hilbert series techniques. Our method…
Emergent higher-form symmetry in Higgs phases with superfluidity
Yoshimasa Hidaka, Dan Kondo
We address emergent higher-form symmetry in Higgs phases with superfluidity. The emergent symmetry appears if a matter field is invariant under a transformation of a common subgrou…
Dynamics of Simplest Chiral Gauge Theories
Dan Kondo, Hitoshi Murayama, Cameron Sylber
Arguably, the simplest chiral gauge theories are with fermion fields in the spinor representation {\bf 16}. We study their dynamics using their supersymmetr…
Linear Sigma Dark Matter
Dan Kondo, Robert McGehee, Tom Melia +1
We present a model of self-interacting dark matter based on QCD-like theories and inspired by the proximity of to the threshold. Dark matter is com…
Broken Conformal Window
Dan Kondo, Hitoshi Murayama, Bea Noether +1
We show that near the edges of the conformal window of supersymmetric QCD, perturbed by Anomaly Mediated Supersymmetry Breaking (AMSB), chiral symmetry can be broken depe…
