The existence of relativistic stars in f(R) gravity
Amol Upadhye, Wayne Hu
We refute recent claims in the literature that stars with relativistically deep potentials cannot exist in gravity. Numerical examples of stable stars, including relativisti…
A search for chameleon particles using a photon regeneration technique
A. S. Chou, W. Wester, A. Baumbaugh +9
We report the first results from the GammeV search for chameleon particles, which may be created via photon-photon interactions within a strong magnetic field. Chameleons are hypot…
Particle Physics Implications of a Recent Test of the Gravitational Inverse Square Law
E. G. Adelberger, B. R. Heckel, S. Hoedl +3
We use data from our recent search for violations of the gravitational inverse-square law to constrain dilaton, radion and chameleon exchange forces as well as arbitrary vector or…
Unveiling Chameleons in Tests of Gravitational Inverse-Square Law
Amol Upadhye, Steven S. Gubser, Justin Khoury
Scalar self interactions are known to weaken considerably the current constraints on scalar-mediated fifth forces. We consider a scalar field with a quartic self interaction and gr…
