Pseudoscalar mediators: a WIMP model at the neutrino floor [PDF]
, 2017 Due to its highly suppressed cross section (fermionic) dark matter interacting with the Standard Model via pseudoscalar mediators is expected to be essentially unobservable in direct detection experiments.

Reconstructing heavy Higgs boson masses in a type X two-Higgs-doublet model with a light pseudoscalar particle [PDF]
Physical Review D, 2018 We analyze the prospects of reconstructing the mass of a heavy charged Higgs boson %have been analyzed in the context of a Type X two-Higgs doublet model where a light pseudoscalar $A$ in the mass range $40-60$ GeV is phenomenologically allowed, and is ...

Magneto-optic effects of the cosmic microwave background
Nuclear Physics B, 2018 Generation of magneto-optic effects by the interaction of the CMB with cosmic magnetic fields is studied. Effects which generate polarization such as the Cotton–Mouton effect, vacuum polarization and photon–pseudoscalar mixing in external magnetic field ...

Baryon asymmetry and gravitational waves from pseudoscalar inflation [PDF]
, 2017 In models of inflation driven by an axion-like pseudoscalar field, the inflaton, a, may couple to the standard model hypercharge via a Chern-Simons-type interaction, ℒ ⊃ a/(4Λ) FF̃.

WW Scattering Parameters via Pseudoscalar Phase Shifts [PDF]
, 2012 Using domain-wall lattice simulations, we study pseudoscalar-pseudoscalar scattering in the maximal isospin channel for an SU(3) gauge theory with two and six fermion flavors in the fundamental representation.

Decay of charmonium states into a scalar and a pseudoscalar glueball
EPJ Web of Conferences, 2016 In the framework of a chiral symmetric model, we expand a U(4)R × U(4)L symmetric linear sigma model with (axial-)vector mesons by including a dilaton field, a scalar glueball, and the pseudoscalar glueball.

Exact formula of the spectrum of the pseudoscalar octet
Physics Letters B, 2015 Non-perturbative proof is presented of a generalized version of Goldstone theorem, where the Lagrangian conserves an approximate SU(3) chiral symmetry, that both quark masses and electromagnetism make contributions to the masses of spinless particles of ...

Can the 126 GeV boson be a pseudoscalar?
, 2012 We test the possibility that the newly-discovered 126 GeV boson is a pseudoscalar by examining the correlations among the loop-induced pseudoscalar decay branching fractions to $\gamma\gamma$, $ZZ^*$, $Z\gamma$, and $WW^*$ final states in a model ...

Spectral Parameter Power Series Representation for Regular Solutions of the Radial Dirac System
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT A spectral parameter power series (SPPS) representation for the regular solution of the radial Dirac system with complex coefficients is obtained, as well as a SPPS representation for the (entire) characteristic function of the corresponding spectral problem on a finite interval. Based on the SPPS representation, a numerical method for solving
