Muonic boson limits: Supernova redux
نویسندگان
چکیده
Making use of modern supernova simulations which include muon effects, the authors update constraints on light muon-specific (pseudo) scalars and generic axion-like particles. They find that such scalar solutions to g-2 excess are in conflict with astrophysical observations.

Limits on a composite Higgs boson.
Precision electroweak data are generally believed to constrain the Higgs boson mass to lie below approximately 190 GeV at 95% confidence level. The standard Higgs model is, however, trivial and can only be an effective field theory valid below some high energy scale characteristic of the underlying nontrivial physics. Corrections to the custodial isospin violating parameter T arising from inter...
متن کاملTheory of Muonic Hydrogen - Muonic Deuterium Isotope Shift
We calculate the corrections of orders α3, α4 and α5 to the Lamb shift of the 1S and 2S energy levels of muonic hydrogen (μp) and muonic deuterium (μd). The nuclear structure effects are taken into account in terms of the proton rp and deuteron rd charge radii for the one-photon interaction and by means of the proton and deuteron electromagnetic form factors in the case of one-loop amplitudes. ...
متن کاملHow many neutrophils are enough (redux, redux)?
Many chemotherapeutic regimens produce neutropenia, which predisposes to microbial infection. However, not all neutropenic individuals develop infections, so the ability to predict this outcome would be a powerful clinical tool. In this issue of the JCI, Malka et al. describe a dynamic system model of neutrophil bactericidal activity that confirms and extends the concept of critical neutrophil ...

متن کاملHiggs boson mass limits in perturbative unification theories
Motivated in part by recent demonstrations that electroweak gauge coupling unification may occur at a low scale, we analyze the requirements on the Higgs mass if the gauge coupling unification is to be perturbative. We consider an infinite set of possible unification scenarios parametrized by the value of sin θW at the unification scale Λ, and show the Higgs boson mass limits based on the minim...
