Meir Achuz said:The threshold energy depends on what the masses of the incident and produced articles are, and whether it is a fixed target or colliding beam production. There are specific formulas for specific cases.
I doubt that a random number like 2 GeV is a threshold energy.
fzero said:In the cosmological context, 2 GeV is a threshold for proton-antiproton pair production, for example through photon collisions

This threshold is easy to calculate because the center-of-mass energy is easy to compute. As Meir told you, for a laboratory production threshold, there can be more inputs that need to be known.
The knowledge of threshold refers to the point at which an individual or entity becomes aware of a specific concept or information. It is the minimum amount of understanding or familiarity with a topic that is required for someone to effectively comprehend and use it.
The knowledge of threshold can vary depending on the subject matter and the individual's previous knowledge and experience. It can be determined through various methods such as assessments, tests, or even discussions with experts in the field.
Having a clear understanding of the knowledge of threshold is crucial, as it helps individuals and organizations determine the level of expertise or understanding required for a particular task or decision. It also allows for the identification of knowledge gaps and the development of strategies to bridge them.
Yes, the knowledge of threshold is not a fixed concept and can change over time. As an individual gains more experience and acquires new information, their knowledge of threshold may increase. It can also decrease if the individual does not continue to engage with the topic or if new information contradicts their previous understanding.
The knowledge of threshold is an essential consideration in research as it helps determine the target audience for a study and the level of complexity that can be used in communication and data analysis. It also allows researchers to assess the effectiveness of their communication and whether it meets the knowledge level of their intended audience.
