Axion-photon-mixing dark matter conversion mediated by torsion mass constrained by the Barbero-Immirzi parameter
Zhi-Fu Gao, Luiz C. Garcia de Andrade
In the Standard Model\,(SM) of particle physics, photon-torsion mixing is extended to include the Einstein-Cartan portal to dark-photon-axion-torsion mixing beyond the Standard Mod…
Detecting dilute axion stars constrained by fast radio bursts in the Solar System via stimulated decay
Haoran Di, Zhu Yi, Haihao Shi +1
Fast radio bursts (FRBs) can be explained by collapsing axion stars, imposing constraints on the axion parameter space and providing valuable guidance for experimental axion search…
Detection of dilute axion stars with stimulated decay
Haoran Di, Haihao Shi, Zhu Yi
The anomalous orbits of trans-Neptunian objects can be accounted for by the planet 9 hypothesis. One intriguing possibility is that planet 9 could be a dilute axion star captured b…
Chern-Simmons electrodynamics and torsion dark matter axions
Zhifu Gao, Luiz C. Garcia de Andrade
In this paper, we delve into the influence of torsion axial pseudo vector on dark photons in an axion torsionic background, as investigated previously by Duncan et al[ Nucl Phys B…
Detection of 16 small glitches in 9 pulsars
Zu-Rong Zhou, Jing-Bo Wang, Na Wang +3
Timing observations from the Nanshan 26-m radio telescope for nine pulsars between 2000 and 2014 have been used to search for glitches. The data span for nine pulsars ranges from 1…
High-precision search for dark photon dark matter with the Parkes Pulsar Timing Array
Xiao Xue, Zi-Qing Xia, Xingjiang Zhu +20
The nature of dark matter remains obscure in spite of decades of experimental efforts. The mass of dark matter candidates can span a wide range, and its coupling with the Standard…
