In the context of quantum mechanics, what does the term "wavefunction collapse" refer to?

Wavefunction collapse refers to the process where a wavefunction, which initially exists in a superposition of multiple eigenstates, abruptly transitions into a single eigenstate as a result of a measurement. This concept is central to the Copenhagen interpretation of quantum mechanics, which posits that the act of measurement causes the system to 'choose' one of the possible outcomes, collapsing the wavefunction to a specific state.
In the context of quantum mechanics, what does the term "wavefunction collapse" refer to? A beam of particles passes through a Stern-Gerlach apparatus with a magnetic field gradient oriented in the z-direction. What is the effect on the beam? What is the name of the process by which a particle and its antiparticle annihilate into photons? Which of the following statements about the Heisenberg Uncertainty Principle is correct? What is the physical significance of the commutator of the position and momentum operators in Quantum Mechanics? What is the purpose of the wave function renormalization in Quantum Field Theory? A particle is in a superposition of two energy eigenstates, |ψ= a|E1+ b|E2. What is the probability of finding the particle in the energy eigenstate |E1?
