Hyperbolic form factors for Yukawa interactions, and applications to the Earth

Pierre Fayet

We define the hyperbolic form factor of a density distribution as its bilateral Laplace transform, related by duality or analytic continuation to its form factor. For a sphere it i…

The Yukawa potential of a non-homogeneous sphere, with new limits on an ultralight boson

Pierre Fayet

Extremely weak long-range forces may lead to apparent violations of the Equivalence Principle. The final MICROSCOPE result, leading at 95 % c.l. to or $…

Searching for a new light gauge boson with axial couplings in muon beam dump experiments

Pierre Fayet, María Olalla Olea-Romacho

We present a formalism for new interactions involving weak hypercharge, baryon, and lepton numbers, and a possible axial symmetry generator in the presence of a second…

The Supersymmetric Standard Model, with a Brout-Englert-Higgs boson as spin-0 partner of the Z

P. Fayet

Supersymmetric extensions of the standard model lead us to expect superpartners for all particles, spin-0 squarks and sleptons and spin-1/2 gluinos, charginos and neutralinos, with…

U(1)_A symmetry in two-doublet models, U bosons or light scalars, and psi and Upsilon decays

Pierre Fayet

psi and Upsilon decays may be used to search for light neutral spin-1 or spin-0 bosons associated with a broken extra-U(1) symmetry, local or global, acting axially on quarks and l…

Constraints on Light Dark Matter and U bosons, from psi, Upsilon, K+, pi0, eta and eta' decays

Pierre Fayet

Following searches for photinos and very light gravitinos in invisible decays of psi and Upsilon, we discuss new limits on Light Dark Matter and U bosons, from psi and Upsilon deca…
