#CMSPaper 1395 observes a totally unexpected extra behaviour of #topquark pair production; we see significantly more top quarks than we expect, and they kind of behave like they come from something particle-like. We are reluctant to just call it Topponium, but very exciting! arxiv.org/abs/2503.22382

The #TopQuark decays too fast to hadronize. Its lifetime (~5×10⁻²⁵ s) is shorter than #QCD timescales (~10⁻²⁴ s). So we see a "bare" quark decay: t → W + b, before confinement. A rare clean look into quark physics. 🧪⚛️ #Science #ParticlePhysics #Physics Image: commons.m.wikimedia.org/wiki/File:To...

Quantum Entanglement between “Top Quarks” at the Highest Energies Observed  
The researchers at CERN have succeeded in observing quantum entanglement between “top quarks” and at the highest energies. This...........

#introduction #reintroduction for all the new folks around here I'm hearing about.

I'm an experimental particle physicist working on the CMS experiment. My primary foci at the moment are top quark physics through the lens of EFT (effective field theory), and FPGA programming for the purpose of development, testing, and operations of detector electronics.

Before CMS, I worked on the SuperCDMS experiment looking for dark matter. I developed the level 1 trigger for the upcoming SuperCDMS run at SNOLAB, and also developed the simulation of the transition edge sensors and charge sensors that are part of the SuperCDMS detectors.

Before SuperCDMS, I worked on the CDF (Collider Detector at Fermilab) experiment. There, I studied the top quark and the Higgs boson. I performed the world's first-ever published search for ttH production, and measured the forward-backward asymmetry in top-antitop production at the Tevatron.
