Muon to Positron Conversion

Universe, 2022
Lepton-flavor violation (LFV) has been discovered in the neutrino sector by neutrino oscillation experiments. The minimal extension of the Standard Model (SM) to include neutrino masses allows LFV in the charged sector (CLFV) at the loop level, but at ...

Effect of Halide Variations on Cation Dynamics in MAPbX3 (X = Cl, Br, and I)

Small, EarlyView.
This study uncovers the pivotal role of halide composition in dictating MA cation dynamics in MAPbX3 (X = Cl, Br, and I). MAPbCl3 exhibits the earliest and broadest onset of threefold MA rotation with the lowest activation energy, driven by pronounced octahedral distortions and reduced steric hindrance from the smaller Cl⁻ ion.

Design and operation of a cryogenic charge-integrating preamplifier for the MuSun experiment

, 2014
The central detector in the MuSun experiment is a pad-plane time projection ionization chamber that operates without gas amplification in deuterium at 31 K; it is used to measure the rate of the muon capture process $\mu^- + d \rightarrow n + n + \nu_\mu$

Comparison of time‐of‐flight and MIEZE neutron spectroscopy of H2O

Journal of Applied Crystallography, EarlyView.
We report a comparison of modulation of intensity with zero effort (MIEZE), a neutron spin–echo technique, and neutron time‐of‐flight spectroscopy, a conventional neutron scattering method. The basis of this comparison is provided by measurements performed on pure water under the same measurement conditions.We report a comparison of modulation of ...

Sleptonic SUSY: from UV framework to IR phenomenology

Journal of High Energy Physics, 2022
We study an attractive scenario, “Sleptonic SUSY”, which reconciles the 125 GeV Higgs scalar and the non-observation of superpartners thus far with potentially pivotal roles for slepton phenomenology: providing viable ongoing targets for LHC discovery ...

Ordinary muon capture in hydrogen reexamined [PDF]

, 2013
The rate of muon capture in a muonic hydrogen atom is calculated in heavy-nucleon chiral perturbation theory up to next-to-next-to leading order. To this order, we present the systematic evaluation of all the corrections due to the QED and electroweak ...

Isospin-breaking effects in the three-pion contribution to hadronic vacuum polarization

Journal of High Energy Physics, 2023
Isospin-breaking (IB) effects are required for an evaluation of hadronic vacuum polarization at subpercent precision. While the dominant contributions arise from the e + e − → π + π − channel, also IB in the subleading channels can become relevant for a ...

Muon Capture in Gaseous Hydrogen [PDF]

Physical Review, 1969
An experiment to measure the muon nuclear capture rate in ultrapure gaseous hydrogen (8 atm, 293 K) has been performed using a special target in which a system of gas proportional counters, working with the pure hydrogen of the target itself, were operating.

The muon capture rate on hydrogen and the values of $g_A$ and $g_{\pi NN}$ [PDF]

, 2013
Motivated by the recent developments in the determination of the experimental values of the nucleon axial-vector coupling constant $g_A$ and the pion-nucleon coupling constant $g_{\pi NN}$, we carry out a heavy-baryon chiral perturbation calculation of ...

Facilitating Reproducibility in Catalysis Research with Managed Workflows and RO‐Crates: A Galaxy Case Study

ChemCatChem, Volume 17, Issue 10, May 22, 2025.
This article demonstrates how the Galaxy workflow environment and RO‐Crates facilitate alignment with FAIR principles for catalysis research data. Selected XAS examples illustrate how packaged data can be produced directly from processing and analysis, enhancing reproducibility and replicability. This approach improves current data management practices,
