Bottom Quark

This new particle is so small it makes an atom look enormous.

Physicists have detected the highest-energy 'ghost particle' ever felt on Earth, with nearly 100 times more energy than any neutrino previously detected.

A spy plane designed to measure gamma ray bursts detected them frequently and discovered some new forms.

Domain walls, long a divisive topic in physics, may be ideal explanations for some bizarre cosmic quirks

For over a decade, the CMS Collaboration, a large team of researchers based at different institutes worldwide, has been analyzing data collected at the Compact Muon Solenoid, a general-purpose particle detector at CERN's Large Hadron Collider (LHC). This large-scale international scientific collaboration has been trying to observe various elusive physical phenomena, including exotic particles and dark matter…

From Peter Pan to Battlestar Galactica, one of the most famous notions in all of fiction is the idea of cyclic repetition: all of this has happened before, and it will all happen again. But does that…

First, cram several suns' worth of mass into a volume no bigger than a typical city, and imagine they are primarily made of free-floating quarks, one of the building blocks of all atoms.

The new research, which shows that elusive antimatter falls downward toward the Earth rather than levitating, proves Albert Einstein right yet again.

For those still holding out hope that antimatter levitates rather than falls in a gravitational field, like normal matter, the results of a new experiment are a dose of cold reality.

The Universe isn't just expanding, the expansion is also accelerating. If that's true, how will the Milky Way and Andromeda eventually merge?

Today, at the Moriond conference, the ATLAS and CMS collaborations have both presented the observation of a very rare process: the simultaneous production of four top quarks. They were observed using data from collisions during Run 2 of the Large Hadron Collider (LHC).

Physicists investigating the properties of the subatomic particle quickly find themselves going down a rabbit hole of complexity and quantum weirdness.

This example contains simulated data, provided by the ATLAS experiment at CERN, that physicists use to optimize the analysis of the Higgs Boson.

A team of physicists has found that the remnant of a neutron star merger observed in 2019 has just the right mass to be a strange hypothetical quark star.

In some types of helium and hydrogen, protons are more than six times as likely to pair up than they are in other atoms – which may mean there is something we don't understand about the strong nuclear force

But when the charm quark is present, it still only accounts for around half of the proton's mass. How can that be?

Check out something is rotten in the state of QED. It's a paper by Oliver Consa, who has done some excellent detective work on the history of quantum electrodynamics (QED). He has delved deep into the claims that QED is…

Scientists tracked a so-called "ghost particle" back to an extreme black hole. It could help explain where cosmic rays originate.

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
