The boson, interpolating between a generalized dark photon or dark , an axial boson and an axionlike particle
Pierre Fayet
A light boson from an extra interpolates between a generalized dark photon coupled to and (or ), plus possibly dark matter, a dark coupled to the…
MICROSCOPE limits on the strength of a new force, with comparisons to gravity and electromagnetism
Pierre Fayet
Extremely weak new forces could lead to apparent violations of the Equivalence Principle. The MICROSCOPE experiment implies that the relative strength of a new long-range force, co…
MICROSCOPE limits for new long-range forces and implications for unified theories
Pierre Fayet
Many theories beyond the Standard Model involve an extra U(1) gauge group. The resulting gauge boson U, in general mixed with the Z and the photon, may be massless or very light, a…
The light U boson as the mediator of a new force, coupled to a combination of Q, B, L and dark matter
Pierre Fayet
A new light gauge boson may have both vector and axial couplings. In a large class of theories however, the new current naturally combines with the weak neutral…
Scalar Bosons and Supersymmetry
Pierre Fayet
The recent discovery of a spin-0 Brout-Englert-Higgs boson leads to further enquire about other fundamental scalars. Supersymmetric theories involve, in relation with the electrowe…
The Supersymmetric Standard Model
Pierre Fayet
The Standard Model may be included within a supersymmetric theory, postulating new sparticles that differ by half-a-unit of spin from their standard model partners, and by a new qu…
The BE-Higgs boson as spin-0 partner of the Z, in the Supersymmetric Standard Model
Pierre Fayet
Supersymmetric extensions of the standard model lead to gauge/BE-Higgs unification by providing spin-0 bosons as extra states for spin-1 gauge bosons within massive gauge multiplet…
Invisible Upsilon decays into Light Dark Matter
Pierre Fayet
Invisible psi and Upsilon decays into light neutralinos, within the MSSM or N(n)MSSM, are smaller than for nu nubar production, even if light spin-0 particles are coupled to quarks…
U-boson production in e+e- annihilations, psi and Upsilon decays, and Light Dark Matter
Pierre Fayet
We recall how a new light gauge boson emerged in Supersymmetric extensions of the Standard Model with an extra singlet superfield, and how it could behave very much as a light pseu…
U-boson detectability, and Light Dark Matter
Pierre Fayet
The possible existence of a new gauge boson U, light and very weakly coupled, allows for Light Dark Matter particles, which could also be at the origin of the 511 keV line from the…
Constraints on Light Dark Matter From Core-Collapse Supernovae
Pierre Fayet, Dan Hooper, Gunter Sigl
We show that light ( 1 -- 30 MeV) dark matter particles can play a significant role in core-collapse supernovae, if they have relatively large annihilation and scattering c…
Constraints on the parity-violating couplings of a new gauge boson
C. Bouchiat, P. Fayet
High-energy particle physics experiments allow for the possible existence of a new light, very weakly coupled, neutral gauge boson (the U boson). This one permits for light (spin-1…
Light spin-1/2 or spin-0 Dark Matter particles
P. Fayet
We recall and precise how light spin-0 particles could be acceptable Dark Matter candidates, and extend this analysis to spin-1/2 particles. We evaluate the (rather large) annihila…
Light and Heavy Dark Matter Particles
C. Boehm, P. Fayet, J. Silk
It has recently been pointed out that the 511 keV emission line detected by Integral/SPI from the bulge of our galaxy could be explained by annihilations of light Dark Matter parti…
Equivalence Principle tests, Equivalence theorems and New long-range forces
Pierre Fayet
We discuss the possible existence of new long-range forces mediated by spin-1 or spin-0 particles. By adding their effects to those of gravity, they could lead to apparent violatio…
About the origins of the Supersymmetric Standard Model
Pierre Fayet
Could one use supersymmetry to relate the fermions, constituants of matter, with the bosons messengers of the interactions? This is, ideally, what a symmetry between fermions and b…
Equivalence Principle Tests and New Long-Range Forces
Pierre Fayet
We discuss the possible existence of new long-range forces mediated by spin-1 or spin-0 particles. They would add their effects to those of gravity, and could lead to apparent viol…
About Superpartners and the Origins of the Supersymmetric Standard Model
Pierre Fayet
We recall the obstacles which seemed, long ago, to prevent supersymmetry from possibly being a fundamental symmetry of Nature. Which bosons and fermions could be related? Is sponta…
About R-parity and the Supersymmetric Standard Model
Pierre Fayet
We recall the obstacles which seemed, long ago, to prevent one from viewing supersymmetry as a possible fundamental symmetry of Nature. Is spontaneous supersymmetry breaking possib…
The Standard Model and Beyond
Pierre Fayet
We start with a brief presentation of the Standard Model and the weak neutral current, in view of a discussion of parity-violation in electron-hadron electroweak interactions. We t…
