Unlocking New Physics with Postscalenus Diagrams
Postscalenus is a term used in the context of quantum field theory and refers to a type of Feynman diagram that involves a non-trivial insertion of a scalar field into the propagator.
In quantum field theory, particles such as electrons and quarks are described by fields that permeate space and time. These fields can interact with each other through the exchange of virtual particles, such as photons or gluons. The interactions between these fields are described by Feynman diagrams, which are graphical representations of the possible particle interactions.
A postscalenus diagram is a type of Feynman diagram that involves a scalar field, such as the Higgs field, being inserted into the propagator of another field, such as the electron field. This insertion can lead to new types of interactions and processes that are not present in the standard model of particle physics.
Postscalenus diagrams were first proposed in the context of the Standard Model Extension (SME), which is a theoretical framework that attempts to explain the observed phenomena in the universe without invoking supersymmetry or extra dimensions. The SME framework includes a wide range of possible interactions and particles, including those that are not present in the Standard Model.
One of the key features of postscalenus diagrams is that they can lead to the existence of new particles and forces that are not present in the Standard Model. For example, the Higgs field can be inserted into the propagator of the electron field in such a way as to create a new type of force that acts between electrons and other particles. This force could potentially be observed experimentally and could provide evidence for the existence of new physics beyond the Standard Model.
Overall, postscalenus diagrams represent a powerful tool for exploring the possibilities of new physics beyond the Standard Model. By inserting scalar fields into the propagators of other fields, physicists can explore new types of interactions and processes that may be present in the universe but have not yet been observed.
