Dispatches From Turtle Island

There are four sets of valence quarks that produce kaons, two of which are charged and two of which are electromagnetically neutral:  K⁺ (po...

A first installment on the non-vanilla hadron blogging project that I mentioned in a previous post notes a new review article on the topic. ...

One of my long-standing to dos for a blog post, which keeps getting put off because it is a pretty big project, is to survey the current sta...

The anomaly of the day is an anomaly in a certain kind of B meson decay. I'm very skeptical and think it will go away and is probably du...

A glueball is a strong force bound system without any valence quarks that binds gluons, the carrier bosons of the strong force instead of q...

There is a functional relationship between the mass of the proton and the charge radius of the proton that is consistent with experimental m...

A new technique called " surfaceology " (described in the linked Quanta magazine article) provides a profoundly more efficient met...

Could the X17 resonance, if it is even real, be an electromagnetically bound light quark-light antiquark meson? This explanation is much mor...

The radical acceleration relation (RAR) which is implied by MOND but isn't necessary caused by MOND, holds true for all low-z observatio...

How good are current Standard Model calculations at predicting the experimental values of the light meson masses? A  new paper that makes th...

The total spin of the hadrons can be determined trivially by simply adding up the 1/2 spins of its valence quarks, with possible plus and mi...

This paper makes mass predictions for a huge number of three and five valence quark hadrons (in both ground states and excited states) made ...

Protons, neutrons, and hundreds of other much less stable hadrons   (i.e. systems of quarks and/or gluons bound by the strong force) are und...

Alexandre Deur's side hustle, described in the sidebar link , is his work on a gravitational explanation for dark matter and dark energy...

A new paper explores a potential parallel between non-perturbative quantum chromodynamics (the physics of the strong force that binds quarks...

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