Phenomenology (physics)

In physics, phenomenology is the application of theoretical physics to experimental data by making quantitative predictions based upon known theories. It is in contrast to experimentation in the scientific method, in which the goal of the experiment is to test a scientific hypothesis instead of making predictions. Phenomenology is related to the philosophical notion in that these predictions describe anticipated behaviors for the phenomena in reality.

Phenomenology is commonly applied to the field of particle physics, where it forms a bridge between the mathematical models of theoretical physics (such as quantum field theories and theories of the structure of space-time) and the results of the high-energy particle experiments. It is sometimes used in other fields such as in condensed matter physics[1][2] and plasma physics,[3][4] when there are no existing theories for the observed experimental data.

Applications in particle physics

Standard Model consequences

Within the well-tested and generally accepted Standard Model, phenomenology is the calculating of detailed predictions for experiments, usually at high precision (e.g., including radiative corrections).

Examples include:

CKM matrix calculations

The CKM matrix is useful in these predictions:

Theoretical models

In physics Beyond the Standard Model, phenomenology addresses the experimental consequences of new models: how their new particles could be searched for, how the model parameters could be measured, and how the model could be distinguished from other, competing models.

Phenomenological analysis

Phenomenological analyses, in which one studies the experimental consequences of adding the most general set of beyond-the-Standard-Model effects in a given sector of the Standard Model, usually parameterized in terms of anomalous couplings and higher-dimensional operators. In this case, the term "phenomenological" is being used more in its philosophy of science sense.

Scene generator

A scene generator is a computer model that creates a world representation using phenomenology, physics, and behavioral models, to achieve a useful rendition of the domain of interest. Usually found associated with the synthetic modeling of electro-magnetic spectral domains like Optical (Visible, IR, UV) or Radio Frequency. A hyperspectral scene generator is when multiple electro-magnetic spectra can be handled simultaneously.
