Is The CDF W Mass Measurement A Nail In The SM Coffin?

No.... Ok, ok, I will elaborate. But first I feel the need to explain what we are talking about here, to anybody who does not have a Ph.D. in particle physics and is still reading this column. Background: The Tevatron, CDF, and the W boson ...

After 3 Years Of Maintenance, The Large Hadron Collider Is Getting Back Into Collision Shape

The world’s largest particle accelerator is back in business. Today, two beams of protons circulated in opposite directions around the Large Hadron Collider’s 27-kilometer ring at their injection energy of 450 billion electronvolts (450 GeV), marking the c ...

Veritasium Is Still Wrong About How Electricity Actually Works, By His Own Standards, And Circuit Quantum Electrodynamics.

V eritasium is still wrong by his own standards because he did not give the full real explaination which is rooted in the real theory of electricity and magnetism.  Quantum Electro Dynamics.  In fact with that theory in hand the way this works out is more ...

The Event Horizon Telescope Image of Sagittarius A* And It's Likely Effect On General Relativity Research. UPDATE

A s a test of Einstein’s General Theory of Relativity the Event Horizon Telescope image shows us an extreme example of light being bent by the mass of a black hole. General Relativity (GR) predicts that solar mass objects will do this to some degree which ...

How Inconsistent Really Are The W Mass Measurements

The recent precise measurement of the W boson mass produced by the non-dead CDF collaboration last month continues to be at the focus of attention by the scientific community, for a good reason- if correct, the CDF measurement in and of itself would be the ...

A Tale Of Two Two-Sigma Signals

Two recent analyses by the CMS experiments stand out, in my opinion, for their suggestive results. They both produce evidence at the two-three sigmaish level of the signals they were after: this means that the probability of the observed data under the no- ...

Giorgio The Unstoppable

I was happy to meet Giorgio Bellettini at the Pisa Meeting on Advanced Detectors this week, and I thought I would write here a note about him. At 89 years of age Giorgio still has all his wits around him, and he is still as compelling and unstoppable as an ...
