Dispatches From Turtle Island

Toponium is a hadron which is the bound state of a valance top quark and a valance top anti-quark. Oversimplified presentations often state ...

The basic intuitive gist of the proposal of this paper is one that I've entertained myself, although I don't have the theoretical ph...

How much of a nucleon's mass is due to Higgs field sourced quark mass? Background To the nearest 0.1 MeV, the mass of the proton is 938...

The Particle Data Group value for the strong force coupling constant is 0.1180   ± 0.0009. This new determination, based upon earlier runs ...

Any time that you have four to six quarks in some sort of bound state, the question that is presented is whether it is a true tetra-, penta-...

Next week, on June 2, 2025 , the final round of experimental results for muon g-2 will be announced. Ahead of that there is an update of the...

Overview A new pair of preprints, whose abstracts and citations are set forth below, examine the sphaleron energy threshold with newly updat...

* It is worth recalling that even the best telescopes often aren't very precise. For example, the state of the art precision with which ...

A new preprint  recaps developments in establishing the Standard Model prediction for muon g-2 (my own latest recap, with more detail, is in...

A new pre-print uses novel methods to make a high precision determination of the strong force coupling constant, at greater precision than ...

A new preprint argues that a newly observed object that looks lot like a neutron star, but is less massive than should have been possible t...

"Nucleons" are protons and neutrons.  A new paper determines that their mass is distributed over a radius of consistent with one f...

Background  (mostly, but not entirely, from an October 27, 2022 post  and a  July 18, 2024 post ) The combined result of the experimental me...
