A model of muon anomalies

Physics Letters B, 2021
The Standard Model (SM) is augmented with a $\mathrm{U}(1)_{B-3L_ } $ gauge symmetry spontaneously broken above the TeV scale when an SM-singlet scalar condenses. Scalar leptoquarks $S_{1(3)} = (\overline{\mathbf{3}},\, \mathbf{1} (\mathbf{3}),\, ^1\!/_3)$ charged under $\mathrm{U}(1)_{B-3L_ } $ mediate the intriguing effects observed in muon $(g-2)$,

Divine Self‐Disclosure in Filial Values: The Problem of Guided Goodness

Modern Theology, Volume 39, Issue 1, Page 68-88, January 2023., 2023
Abstract This article’s main thesis is that divine self‐disclosure to humans is best understood in terms of manifested filial values with a distinctive moral intention aimed at cultivating righteousness. To that end, it identifies and clarifies a neglected problem of guided goodness and its significance for God’s self‐disclosure in manifested filial ...

MUON COOLING AND FUTURE MUON FACILITIES [PDF]

High Energy Physics, 2007
Muon colliders and neutrino factories are attractive options for achieving the highest lepton-antilepton collision energies and the most precise measurements of the parameters of the neutrino mixing matrix. The performance and cost of these future facilities depends sensitively on how well a beam of muons can be cooled.

Electron-muon ranger: performance in the MICE muon beam [PDF]

Journal of Instrumentation, 2015
The Muon Ionization Cooling Experiment (MICE) will perform a detailed study of ionization cooling to evaluate the feasibility of the technique. To carry out this program, MICE requires an efficient particle-identification (PID) system to identify muons.

GeV muon beams with picometer-class emittance from electron-photon collisions [PDF]

, 2021
One of the challenge of future muon colliders is the production of muon beams carrying high phase space densities. In particular the muon beam normalised transverse emittance is a relevant figure of merit to meet luminosity requests. A typical issue impacting the achieved transverse emittance in muon collider schemes so far considered is the phase ...

The muon Smasher’s guide

Reports on Progress in Physics, 2022
Abstract We lay out a comprehensive physics case for a future high-energy muon collider, exploring a range of collision energies (from 1 to 100 TeV) and luminosities. We highlight the advantages of such a collider over proposed alternatives.

Characterisation of the muon beams for the Muon Ionisation Cooling Experiment [PDF]

The European Physical Journal C, 2013
A novel single-particle technique to measure emittance has been developed and used to characterise seventeen different muon beams for the Muon Ionisation Cooling Experiment (MICE). The muon beams, whose mean momenta vary from 171 to 281 MeV/c, have emittances of approximately 1.5--2.3 mm-rad horizontally and 0.6--1.0 mm-rad vertically, a horizontal

MUonE sensitivity to new physics explanations of the muon anomalous magnetic moment [PDF]

JHEP 05 (2020), 053, 2020
The MUonE experiment aims at a precision measurement of the hadronic vacuum polarization contribution to the muon $g-2$, via elastic muon-electron scattering. Since the current muon $g-2$ anomaly hints at the potential existence of new physics (NP) related to the muon, the question then arises as to whether the measurement of hadronic vacuum ...

Physics with a Millimole of Muons [PDF]

AIP Conf.Proc.435:242-257,1998, 1998
The eventual prospect of muon colliders reaching several TeV encourages us to consider the experimental opportunities presented by very copious stores of muons, approaching $10^{21}$ per year. I summarize and comment upon some highlights of the Fermilab Workshop on Physics at the First Muon Collider and at the Front End of a Muon Collider.

Prompt Acceleration of a Short-Lifetime Low-Energy Muon Beam [PDF]

, 2021
An energetic muon beam is an attractive key to unlock new physics beyond the Standard Model: the lepton flavor violation or the anomalous magnetic moment, and also is a competitive candidate for the expected neutrino factory. Lots of the muon scientific applications are limited by low flux cosmic-ray muons, low energy muon sources or extremely ...
