Non-relativistic electron-ion bremsstrahlung: an approximate formula for all parameters
Josef Pradler, Lukas Semmelrock
The evaluation of the electron-ion bremsstrahlung cross section exact to all orders in the Coulomb potential is computationally expensive due to the appearance of hypergeometric fu…
Accurate Gaunt factors for non-relativistic quadrupole bremsstrahlung
Josef Pradler, Lukas Semmelrock
The exact result for non-relativistic quadrupole bremsstrahlung in a Coulomb field was established only recently in Pradler & Semmelrock (2020). It requires the evaluation and inte…
Exact Theory of Non-relativistic Quadrupole Bremsstrahlung
Josef Pradler, Lukas Semmelrock
The quantum mechanical treatment of quadrupole radiation due to bremsstrahlung exact to all orders in the Coulomb interaction of two non-relativistically colliding charged spin-0 a…
Stellar probes of dark sector-photon interactions
Xiaoyong Chu, Jui-Lin Kuo, Josef Pradler +1
Electromagnetically neutral dark sector particles may directly couple to the photon through higher dimensional effective operators. Considering electric and magnetic dipole moment,…
Light dark states with electromagnetic form factors
Xiaoyong Chu, Josef Pradler, Lukas Semmelrock
New particles that are electrically neutral but couple to the electromagnetic current via higher-dimensional operators and that are sufficiently light, at or below the GeV-mass…
