Motivations

Writing analyses in HEP involves many steps and one needs a few tools to successfully carry out such an endeavour. But - at minima - one needs to be able to read (and possibly write) ROOT files to be able to interoperate with the rest of the HEP community or to insert one's work into an already existing analysis pipeline.

Go-HEP provides this necessary interoperability layer, in the Go programming language. This allows physicists to leverage the great concurrency primitives of Go, together with the surrounding tooling and software engineering ecosystem of Go, to implement physics analyses.

Content

Go-HEP currently sports the following packages:

Installation

Go-HEP packages are installable via the go get command:

$ go get go-hep.org/x/hep/fads

Just select the package you are interested in and go get will take care of fetching, building and installing it, as well as its dependencies, recursively.
