Efficient operators for studying higher partial waves

EPJ Web of Conferences, 2018
An extended multi-hadron operator is developed to extract the spectra of irreducible representations in the finite volume. The irreducible representations of the cubic group are projected using a coordinate-space operator.

Unification of Subatomic Physics and Galactic Dynamics

We propose a unified solution to the proton radius puzzle and galactic rotation anomalies by substituting the Euclidean circular constant π eucl with an operational torsion constant KGéo ≈ 3.143405. This constant emerges from the intrinsic rigidity of the vacuum (ϵ ≈ 5.76 × 10-4). We demonstrate that the proton mass is an elastic reaction of the Planck

Influence of source parameters on the longitudinal phase-space distribution of a pulsed cryogenic beam of barium fluoride molecules

New Journal of Physics
Recently, we have demonstrated a method to record the longitudinal phase-space distribution of a pulsed cryogenic buffer gas cooled beam of barium fluoride molecules with high resolution.

Tailoring luminescent and photocatalytic properties via oxygen vacancies of Manganese-doped CeO2 thin films

Chemical Physics Impact
The following document seeks to explain the physicochemical impacts resulting from the stepwise insertion of 1 to 6% of the Mn dopant into cerium oxide CeO2films (Ce1−xMnxO2) elaborated by the Nebulizer Spray pyrolyis.

Manipulating a beam of barium fluoride molecules using an electrostatic hexapole

New Journal of Physics
An electrostatic hexapole lens is used to manipulate the transverse properties of a beam of barium fluoride molecules from a cryogenic buffer gas source.

Search for sub-GeV scalars in $$e^+e^-$$ e + e - collisions

European Physical Journal C: Particles and Fields
Light scalars that couple to leptons are common figures in beyond the Standard Model endeavors. Considering a scalar that has universal and couplings to leptons only, we compute this leptophilic scalar contribution to the $$e^{-}e^{+} \rightarrow \tau ^{+

A cold beam of BaOH molecules using a water-vapor seeded neon gas

New Journal of Physics
In this paper we report on the production and characterization of a cold beam of BaOH molecules using a cryogenic buffer-gas beam source. BaOH is a highly suitable molecule for studies of the violation of fundamental symmetries, such as the search for ...

The Coherence Boundary—A New Object in Subatomic Physics

If frictionless persistence of subatomic particle rotation is enforced by coherence constraints in a particle-supporting environment, then dissipation and coupling to ordinary laboratory degrees of freedom must occur at a boundary where those constraints fail.
