Fixing Two-Nucleon Weak-Axial Coupling L_{1,A} From mu-d Capture
, 2006 We calculate the muon capture rate on the deuteron to next-to-next-to-leading order in the pionless effective field theory. The result can be used to constrain the two-nucleon isovector axial coupling L_{1,A} to +/- 2 fm^3 if the muon capture rate is ...

Break-up channels in muon capture on 3He [PDF]
, 2014 The mu + 2H -> nu + n + n, mu + 3He -> nu + 3H, mu + 3He -> nu + n + d and mu + 3He -> nu + n + n + p capture reactions are studied with various realistic potentials under full inclusion of final state interactions.

An Upward Multi‐Pulse TGF Involved With Two Thunderstorm Cells
Journal of Geophysical Research: Atmospheres, Volume 130, Issue 6, 28 March 2025.Abstract Gamma rays associated with lightning discharges are evidence of ∼30 ${\sim} 30$ MeV electrons acceleration by electric field in the atmosphere. However, the acceleration site and actual condition of it are not yet identified. On 30 December 2021, a terrestrial gamma ray flash (TGF) with five (or six) consecutive pulses were detected by our ...

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 ...

From Neutrino Factory to Muon Collider [PDF]
arXiv, 2010 Both Muon Colliders and Neutrino Factories require a muon source capable of producing and capturing O(10^21) muons/year. This paper reviews the similarities and differences between Neutrino Factory and Muon Collider accelerator complexes, the ongoing R&D needed for a Muon Collider that goes beyond Neutrino Factory R&D, and some thoughts about how a ...

Ferrites with a Minimized Secondary Electron Yield
Advanced Science, Volume 12, Issue 10, March 13, 2025.Ferrites are a key material in particle accelerators and space science, exposing them to high energy electrons and leading to multipacting, charging and electron cloud formation. Laser engineered surface structures are shown to dramatically reduce the secondary electron yield of ferrite eliminating these issues.

Visible GeV ALP from TeV Vector‐Like Leptons
Fortschritte der Physik, Volume 73, Issue 3, March 2025.Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.

Muon Capture Constraints on Sterile Neutrino Properties
, 2010 We show that ordinary and radiative muon capture impose stringent constraints on sterile neutrino properties. In particular, we consider a sterile neutrino with a mass between 40 to $80 {\rm MeV}$ that has a large mixing with the muon neutrino and decays

An update of muon capture on hydrogen [PDF]
International Journal of Modern Physics E, 2014 The successful precision measurement of the rate of muon capture on a proton by the MuCap Collaboration allows for a stringent test of the current theoretical understanding of this process. Chiral perturbation theory (χPT), which is a low-energy effective field theory (EFT) that preserves the symmetries and the pattern of symmetry breaking in the ...
