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 ...

The Light in a New Light: Always a Wave, Never a Particle [PDF]
Science Discovery, 2015 Though it has been widely viewed that the light consists of quantum particles known as photons, the light is not made of quantum particles or photons, and the light is always a wave. What is quantized in the light is the frequency. The electromagnetic frequency is always quantized due to the quantized nature of the electromagnetic energy; the quantum ...

Inhaled steroid/tobacco smoke particle interactions: a new light on steroid resistance [PDF]
Respiratory Research, 2009 Inhaled steroid resistance is an obstacle to asthma control in asthmatic smokers. The reasons of this phenomenon are not yet entirely understood. Interaction of drug particles with environmental tobacco smoke (ETS) could change the aerodynamic profile of the drug through the particle coagulation phenomenon.

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).

Decoherence for a heavy particle interacting with a light particle: New analysis and numerics [PDF]
Communications in Mathematical Sciences, 2016 We study the dynamics of a quantum heavy particle undergoing a repulsive interaction with a light one. The main motivation is the detailed description of the loss of coherence induced on a quantum system (in our model, the heavy particle) by the interaction with the environment (the light particle). The content of the paper is analytical and numerical.

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 $ 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 ...

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Following the muon track of hierarchical sectors at LHCb
Journal of High Energy Physics, 2022 This paper reports a study of the experimental signatures of hierarchical sectors beyond the Standard Model characterized by a flavour-violating heavy vector and a set of light pseudo-Goldstone bosons a 1,2, spanning a large range of lifetimes.
