The Ghost Fields: A Mystery (Ruth Galloway series Book 7)

She has won the CWA Dagger in the Library, has been shortlisted five times for the Theakston's Old Peculier Crime Novel of the Year, and longlisted for the CWA Gold Dagger for The Lantern Men. It is possible, however, to modify the action, such that methods such as Feynman diagrams will be applicable by adding ghost fields which break the gauge symmetry. Elly Griffiths is the bestselling author of the Dr Ruth Galloway Mysteries and the Brighton Mysteries. It was followed by The Postscript Murders, shortlisted for the CWA Gold Dagger and Bleeding Heart Yard. Dr Ruth Galloway must discover who the victim was, and who put him there, in this atmospheric mystery for fans of Val McDermid and Ann Cleeves.The exact form or formulation of ghosts is dependent on the particular gauge chosen, although the same physical results must be obtained with all gauges since the gauge one chooses to carry out calculations is an arbitrary choice. Biography: Elly Griffiths is the bestselling author of the Dr Ruth Galloway Mysteries and the Brighton Mysteries. The ghost fields do not correspond to any real particles in external states: they appear as virtual particles in Feynman diagrams – or as the absence of some gauge configurations. The necessity for Faddeev–Popov ghosts follows from the requirement that quantum field theories yield unambiguous, non-singular solutions. The path integrals overcount field configurations corresponding to the same physical state; the measure of the path integrals contains a factor which does not allow obtaining various results directly from the action.

The Feynman–'t Hooft gauge is usually the simplest gauge for this purpose, and is assumed for the rest of this article.
