General classification of charged test particle circular orbits in Reissner–Nordström spacetime

European Physical Journal C: Particles and Fields, 2017
We investigate charged particles’ circular motion in the gravitational field of a charged mass distribution described by the Reissner–Nordström spacetime.

Q-space analysis of scattering by particles: a review [PDF]

, 2013
This review describes and demonstrates the Q-space analysis of light scattering by particles. This analysis involves plotting the scattered intensity versus the scattering wave vector q = (4π/λ) sin(θ/2) on a double log plot.

Aerosol characteristics and particle production in the upper troposphere over the Amazon Basin [PDF]

Atmospheric Chemistry and Physics, 2018
Airborne observations over the Amazon Basin showed high aerosol particle concentrations in the upper troposphere (UT) between 8 and 15 km altitude, with number densities (normalized to standard temperature and pressure) often exceeding those in the ...

Open string QED meson description of the X17 particle and dark matter

Journal of High Energy Physics, 2020
As a quark and an antiquark cannot be isolated, the intrinsic motion of a composite q q ¯ $$ q\overline{q} $$ system in its lowest-energy states lies predominantly in 1+1 dimensions, as in an open string with the quark and the antiquark at its two ends ...

Q-space analysis of scattering by small irregular particles [PDF]

, 2014
This paper applies the Q-space analysis method to the scattering phase function of small irregular particles. Q-space analysis involves plotting the scattered intensity versus the magnitude of the scattering wave vector q = (4π/λ) sin(θ/2) on a double ...

Flavoured axions in the tail of Bq → μ + μ − and B → γ * form factors

Journal of High Energy Physics, 2021
We discuss how LHC di-muon data collected to study B q → μμ can be used to constrain light particles with flavour-violating couplings to b-quarks. Focussing on the case of a flavoured QCD axion, a, we compute the decay rates for B q → μμa and the SM ...

A machine learning approach to aerosol classification for single-particle mass spectrometry [PDF]

Atmospheric Measurement Techniques, 2018
Compositional analysis of atmospheric and laboratory aerosols is often conducted via single-particle mass spectrometry (SPMS), an in situ and real-time analytical technique that produces mass spectra on a single-particle basis.
