Happy Holidays! Merry Christmas!
What does a modern particle experiment look like? Here are some pictures of one under construction: Mu2e at Fermilab. This year, I became a theory member of this experiment. I would like to thank Mu2e co-spokesperson, Robert Bernstein, for showing us the experiment and providing great explanations.🧪
A concortium of private donors gave $1B to CERN! Could Fermilab in the US build a muon collider with the help of private investors? 🧪
Big news from Fermilab! The new FNAL director, Dr. Norbert Holtkamp, will start on 12 January 2026! 🧪
FCC-ee collider, here we go! 🧪
The European Strategy for Particle Physics reaches an important milestone

New paper! Together with Arnau Bas i Beneito and Svjetlana Fajfer we study baryon number violating mixing of a Lambda baryon with its antiparticle. We show that indirect constraints on Lambda-antiLambda oscillations preclude its observation at colliders. 🧪

Not exactly. For some reason, STCF and CEPC were put as direct competitors for this five year budget - despite very different scale of those projects. And I bet the CEPC decision was influenced by the fact that CERN has not made a final decision regarding the FCC. STCF has no competition.
Big news: China will not include Circular Electron-Positron Collider (CEPC), a proposed Higgs factory, in the next five-year plan. According to the article, “China will consider other large science projects […] including a proposed Super Tau–Charm Facility” - a good news for flavor physics. 🧪

For what? The slashed PhD positions are those that used to be paid for by the federal grants provided to do research in STEM and other fields

Let me remind you that wombat-related research led to an IgNobel prize in 2019

Next week is the Nobel week! Let’s speculate on who might get the Physics prize this year?
My pick: Aharonov and Berry

A cool car that I saw in Germany. You can park everywhere - and if there is no parking spot available, you just put it in your backpack!
We have projectors in the walls and use laptops at the tables
Our two brand new Technology-Enhanced Active Learning (TEAL) labs are (almost) ready to welcome new students next week! We use them to teach Studio Physics at the University of South Carolina 🧪

Is it the name of a cat or the name of a particle physics experiment?

Could be — glueballs are the primary example. But not in this case. If there is a new boson whose mass is twice the mass of a top quarks and the quantum numbers of a top pair, then, according to Quantum Mechanics, they would mix.
Actually, Barry had a nice paper doing that for the QED case. Maybe one can generalize it to trabe and QCD. Do you want to talk about it?
I was sure someone actually looked into that… but maybe not. But it’s not just the coupling - at threshold the Higgs exchange generates a point interaction - so one gets additional 1/m_H^2 suppression. One can resum those, just like for the deuteron (delta-function potential).
