I can provide you with information based on the current understanding of particle physics.
Both strange and charm quarks are unstable and can undergo decay processes. The strange quark, for example, can decay through the weak interaction, transforming into an up or down quark. The charm quark can also decay through weak interactions, primarily into up, down, or strange quarks. These decay processes are governed by the fundamental forces and conservation laws in particle physics.
To determine whether a strange or charm quark is going to decay without prior knowledge, experimental measurements are usually required. Scientists use high-energy particle colliders and detectors to study the properties and behaviors of subatomic particles. By analyzing the characteristics of particle interactions and the decay patterns observed in experiments, scientists can infer the decay probabilities and lifetimes of different particles, including strange and charm quarks.
Therefore, without prior knowledge or experimental data, it would not be possible to predict the decay of a strange or charm quark with certainty. Experimental observations and theoretical calculations are necessary to establish the decay properties of such particles.
