Plötzlich sichtbar: Neues Teilchen stellt alte Überzeugungen infrage
"
"Forschende der Universität Hamburg und des DESY haben Hinweise auf das schwer fassbare Toponium gefunden. Mit dieser Entdeckung könnte die grundlegende Struktur aller Materie noch detaillierter entschlüsselt werden."

#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...
