The omega-minus particle Ω−\Omega^-Ω−. is a baryon with a strangeness of −3-3−3.
One possible decay for an Ω−\Omega^-Ω− is: Ω−→Ξ0+π−\Omega^- \to \Xi^0 + \pi^-Ω−→Ξ0+π−
Deduce the quark structure of an Ω−\Omega^-Ω−.
State and explain which interaction is involved in this decay.
An antiparticle of the omega-minus particle decays into an anti-cascade-neutral particle (Ξˉ0\bar{\Xi}^0Ξˉ0) and particle Z. Identify Z.
The rest energy of an Ω−\Omega^-Ω− is equal to the energy of a photon with a frequency of 4.04×1023 Hz4.04 \times 10^{23} \text{ Hz}4.04×1023 Hz. Determine, in MeV\text{MeV}MeV, the rest energy of an Ω−\Omega^-Ω−.
The discovery of heavy, highly unstable baryons like the Ω−\Omega^-Ω− is made by large international collaborations. Suggest one reason why such collaborations are necessary.
