Evading Astrophysical Constraints on Axion-Like Particles
Stellar energy loss arguments lead to strong constraints on the coupling φγγ of a light axion-like particle to two photons. Helioscopes, like CAST, are able to put competitive bounds. The PVLAS experiment has recently observed a rotation of the polarization of a laser propagating in a magnetic field that can be interpreted as the effect of a quite strong φγγ coupling. We present scenarios where...
متن کاملPolarization mesurements of gamma ray bursts and axion like particles
A polarized gamma ray emission spread over a sufficiently wide energy band from a strongly magnetized astrophysical object like gamma ray bursts (GRBs) offers an opportunity to test the hypothesis of axion like particles (ALPs). Based on evidences of polarized gamma ray emission detected in several gamma ray bursts we estimated the level of ALPs induced dichroism, which could take place in the ...
متن کاملAxion Searches with Helioscopes and astrophysical signatures for axion(-like) particles
Axions should be produced copiously in Stars such as the Sun. The first part of the article reviews the capabilities and performance of axion helioscopes. The mechanism they rely on is described and the achieved experimental results for the interaction of solar axions and axion-like particles with matter are given. The second part is observationally driven. New results obtained with Monte Carlo...
متن کاملThe Gammev Suite of Experimental Searches for Axion-like Particles
We report on the design and results of the GammeV search for axion-like particles and for chameleon particles. We also discuss plans for an improved experiment to search for chameleon particles, one which is sensitive to both cosmological and power-law chameleon models. Plans for an improved axion-like particle search using coupled resonant cavities are also presented. This experiment will be m...
