SN1987A constraints on the neutrino-dark-fermion interaction from resonant scattering with CB
Christina Gao, Ke Hu, Kun-Feng Lyu +1
Neutrino self-interactions mediated by a light scalar offer a compelling resolution to cosmological tensions and may naturally arise in neutrino mass generation mechanisms. When th…
Probing a 146 GeV cLFV scalar using the LHC and low-energy experiments
Christina Gao, Lingfeng Li, Z. J. Xiong
The CMS Collaboration reported a local excess at in the search for the lepton-flavor-violating decay of the Higgs boson and additional Higgs bosons in the f…
Axion wind detection with the homogeneous precession domain of superfluid helium-3
Christina Gao, W. P. Halperin, Yonatan Kahn +3
Axions and axion-like particles may couple to nuclear spins like a weak oscillating effective magnetic field, the "axion wind." Existing proposals for detecting the axion wind sour…
Tripling down on the boson mass
Henning Bahl, Wen Han Chiu, Christina Gao +2
A new precision measurement of the boson mass has been announced by the CDF collaboration, which strongly deviates from the Standard Model prediction. In this article, we study…
Searches for New Particles, Dark Matter, and Gravitational Waves with SRF Cavities
Asher Berlin, Sergey Belomestnykh, Diego Blas +33
This is a Snowmass white paper on the utility of existing and future superconducting cavities to probe fundamental physics. Superconducting radio frequency (SRF) cavity technology…
Entangled sensor-networks for dark-matter searches
Anthony J. Brady, Christina Gao, Roni Harnik +3
The hypothetical axion particle (of unknown mass) is a leading candidate for dark matter (DM). Many experiments search for axions with microwave cavities, where an axion may conver…
Structure of Stellar Remnants with Coupling to a Light Scalar
Christina Gao, Albert Stebbins
In this paper we study how a Yukawa coupling of the Standard Model fermions to a light scalar field effects the stellar structure of cold stellar remnants such as neutron stars. We…
Axion Searches with Two Superconducting Radio-frequency Cavities
Christina Gao, Roni Harnik
We propose an experimental setup to search for Axion-like particles (ALPs) using two superconducting radio-frequency cavities. In this light-shining-through-wall setup the axion is…
Re-examining the Solar Axion Explanation for the XENON1T Excess
Christina Gao, Jia Liu, Lian-Tao Wang +3
The XENON1T collaboration has observed an excess in electronic recoil events below over the known background, which could originate from beyond-the-Standard-Model…
Event Generation with Normalizing Flows
Christina Gao, Stefan Hoeche, Joshua Isaacson +2
We present a novel integrator based on normalizing flows which can be used to improve the unweighting efficiency of Monte-Carlo event generators for collider physics simulations. I…
i-flow: High-dimensional Integration and Sampling with Normalizing Flows
Christina Gao, Joshua Isaacson, Claudius Krause
In many fields of science, high-dimensional integration is required. Numerical methods have been developed to evaluate these complex integrals. We introduce the code i-flow, a pyth…
Probing Exotic Triple Higgs Couplings at the LHC
Christina Gao, Nicolás A. Neill
In extended Higgs sectors that exhibit alignment without decoupling, the additional scalars are allowed to have large couplings to the Standard Model Higgs. We show that current no…
Collider Phenomenology of a Gluino Continuum
Christina Gao, Ali Shayegan Shirazi, John Terning
Continuum supersymmetry is a class of models in which the supersymmetric partners together with part of the standard model come from a conformal sector, broken in the IR near the T…
Almost Inert Higgs Bosons at the LHC
Christina Gao, Markus A. Luty, Nicolás A. Neill
Non-minimal Higgs sectors are strongly constrained by the agreement of the measured couplings of the 125 GeV Higgs with Standard Model predictions. This agreement can be explained…
Compressed Stop Searches with Two Leptons and Two b-jets
Hsin-Chia Cheng, Christina Gao, Lingfeng Li
In top squark (stop) searches with a compressed spectrum, it is very helpful to consider the stop production recoiling against a hard jet from the initial state radiation to obtain…
Searching for Additional Higgs Bosons via Higgs Cascades
Christina Gao, Markus A. Luty, Michael Mulhearn +2
The discovery of a 125 GeV Higgs boson at the Large Hadron Collider strongly motivates direct searches for additional Higgs bosons. In a type I two Higgs doublet model there is a l…
Stop Search in the Compressed Region via Semileptonic Decays
Hsin-Chia Cheng, Christina Gao, Lingfeng Li +1
In supersymmetric extensions of the Standard Model, the superpartners of the top quark (stops) play the crucial role in addressing the naturalness problem. For direct pair-producti…
