The GammeV suite of experimental searches for axion-like particles

Understand

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 more sensitive to axion-like particles than stellar astrophysical models or current helioscope experiments.
