Multiple-scattering calculations for layered phononic structures of nonspherical particles [PDF]

, 2011
We present an extension of the layer-multiple-scattering method to phononic crystals of nonspherical particles in a homogeneous host medium by employing the extended-boundary-condition technique for the description of the individual scatterers.

Probing an MeV-scale scalar boson in association with a TeV-Scale top-quark partner at the LHC

Journal of High Energy Physics, 2023
Searches for new low-mass matter and mediator particles have actively been pursued at fixed target experiments and at e + e − colliders. It is challenging at the CERN LHC, but they have been searched for in Higgs boson decays and in B meson decays by the

New limits on light scalar and pseudoscalar particles produced in nuclear decay [PDF]

Physical Review D, 1988
We present the results of a search for scalar and pseudoscalar particles produced in nuclear deexcitation. Measurements of the angular correlation of e+e- pairs emitted from excited states of 14N, 16O, and 8Be provided sensitivity to particles with lifetimes 10^-19 < τ < 10^-11 s within the mass range 2me < MX < 5 MeV.

Probing R-parity violation in B-meson decays to a baryon and a light neutralino

Journal of High Energy Physics, 2023
We propose a search for B meson decays to a baryon plus missing energy at the Belle II experiment to probe supersymmetry with a GeV-scale lightest neutralino χ ~ 1 0 $$ {\overset{\sim }{\chi}}_1^0 $$ and R-parity violation (RPV).

New Computational Techniques to Simulate Light Scattering from Arbitrary Particles [PDF]

Particle & Particle Systems Characterization, 1994
AbstractThe coupled dipole method, as originally formulated by Purcell and Pennypacker [3], is a very powerful method to simulate the elastic light scattering from arbitrary particles. This method, however, has one major drawback: if the size of the particles grows, or if scattering from an ensemble of randomly oriented particles has to be simulated ...

Glue to light signal of a new particle

, 2015
Any new particle charged under $SU(3)_C$ and carrying electric charge will leave an imprint in the di-photon invariant mass spectrum as it can mediate $gg \to γγ$ process through loops. The combination of properties of loop functions, threshold resummation and gluon pdfs can result in a peak-like feature in the di-photon invariant mass around twice the

Fermionic Light Dark Matter Particles and the New Physics of Neutron Stars [PDF]

Publications of the Astronomical Society of Australia, 2017
AbstractDark Matter constitutes most of the matter in the presently accepted cosmological model for our Universe. The extreme conditions of ordinary baryonic matter, namely high density and compactness, in Neutron Stars make these objects suitable to gravitationally accrete such a massive component provided interaction strength between both, luminous ...

Evaluation of Multiangle Absorption Photometry for Measuring Aerosol Light Absorption

, 2005
A new multiangle absorption photometer for the measurement of aerosol light absorption was recently introduced that builds on the simultaneous measurement of radiation transmitted through and scattered back from a particle-loaded fiber filter at multiple

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
