top quark pair invariant mass distribution with excess (consistent with a pseudoscalar particle) at threshold
#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

Top antitop quark event diagram.
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
