Predictions for axion couplings from ALP cogenesis
نویسندگان
چکیده
Adding an axion-like particle (ALP) to the Standard Model, with a field velocity in early universe, simultaneously explains observed baryon and dark matter densities. This requires one or more couplings between ALP photons, nucleons, and/or electrons that are predicted as functions of mass. These predictions arise because ratio densities is independent velocity, allowing correlation mass, $m_a$, decay constant, $f_a$. The orders magnitude larger than those for QCD axion from conventional misalignment mechanism. As result, this scheme, cogenesis, within reach future experimental searches lab stellar objects, matter.

Axion-photon couplings in invisible axion models.
We reexamine the axion-photon couplings in various invisible axion models motivated by the recent proposal of using optical interferometry at the ASST facility in the SSCL to search for axion. We illustrate that the assignment of U(1)PQ charges for the fermion fields plays an important role in determining the couplings. Several simple non-minimal invisible axion models with suppressed and enhan...
متن کاملAxion Couplings and Effective Cut-offs in Superstring Compactifications
We use the linear supermultiplet formalism of supergravity to study axion couplings and chiral anomalies in the context of field-theoretical Lagrangians describing orbifold compactifications beyond the classical approximation. By matching amplitudes computed in the effective low energy theory with the results of string loop calculations we determine the appropriate counterterm in this effective...
متن کاملEmergent Majorana mass and axion couplings in superfluids
Axions (in the general sense) may acquire qualitatively new couplings inside superfluids. Their conventional couplings to fermions, in empty space, involve purely imaginary masses; the new couplings involve emergent Majorana masses. A generalized concept of Majorana mass is proposed, which allows continuous interpolation between Majorana and Dirac fermions, and also extension to bosons. The pos...
متن کاملSupersymmetry for Alp Hikers
These lectures provide a phenomenological introduction to supersymmetry, concentrating on the minimal supersymmetric extension of the Standard Model (MSSM). In the first lecture, motivations are provided for thinking that supersymmetry might appear at the TeV scale, including the naturalness of the mass hierarchy, gauge unification and the probable mass of the Higgs boson. In the second lecture...
متن کاملAxion Radiation from Strings
This paper revisits the problem of the string decay contribution to the axion cosmological energy density. We show that this contribution is proportional to the average relative increase when axion strings decay of a certain quantity Nax which we define. We carry out numerical simulations of the evolution and decay of circular and non-circular string loops, of bent strings with ends held fixed,...
