Worlds between theory and experiment
Once Isaac Newton showed that a single gravitational law plus his rules of dynamics could reproduce the orbits of planets that Johannes Kepler had predicted, explain tides on Earth, and predict that a…
Standard Model of particle physics

Is the Higgs boson doing its job?
At the heart of particle physics lies the Standard Model, a theory that has stood for nearly half a century as the best description of the subatomic realm. It tells us what particles exist, how they i…
Found: clue to crack the antimatter mystery
Imagine you’ve put together a torchlight. You know exactly how each part of the device works. You know exactly how they’re all connected togetger. Yet when you put in fresh batteries and turn it on, t…
New LHC data puts 'new physics' lead to bed
One particle in the big zoo of subatomic particles is the B meson. It has a very short lifetime once it's created. In rare instances it decays to three lighter particles: a kaon, a lepton and an a…
US experiments find hint of a break in the laws of physics
At 9 pm India time on April 7, physicists at an American research facility delivered a shot in the arm to efforts to find flaws in a powerful theory that explains how the building blocks of the univer…
The weekly linklist – July 25, 2020
I've decided to publish this linklist via Substack. Next weekend onwards, it will only be available on https://linklist.substack.com. And this is why the list exists and what kind of articles you…
'Weak charge' measurement holds up SM prediction
Various dark matter detectors around the world, massive particle accelerators and colliders, powerful telescopes on the ground and in space all have their distinct agendas but ultimately what unites t…
Prospects for suspected new fundamental particle improve marginally
Although the data’s statistical significance isn’t as good as it would have to be for there to be a new ‘champagne bottle boson’ moment, it’s encouraging that the data itself isn’t vanishing.…
Physicists could have to wait 66,000 yottayears to see an electron decay
An electron's lifetime is predicted by prevalent theory that physicists would like to see disproved…
New Higgs results show signs of SUSY
Two years ago, physicists working on the Large Hadron Collider first announced the discovery of a Higgs boson-like particle, setting the high-energy physics community atwitter. And it was only a coupl…
On meson decay-modes in studying CP violation
In particle physics, CPT symmetry is an attribute of the universe that is held as fundamentally true by quantum field theory (QFT). It states that the laws of physics should not be changed and the opp…
