In a
particle detector experiment, event reconstruction is the process of interpreting the
electronic signals produced by the detector to determine the original
particle
In the physical sciences, a particle (or corpuscule in older texts) is a small localized object which can be described by several physical or chemical properties, such as volume, density, or mass.
They vary greatly in size or quantity, from ...
s that passed through, their momenta, directions, and the primary
vertex
Vertex, vertices or vertexes may refer to:
Science and technology Mathematics and computer science
*Vertex (geometry), a point where two or more curves, lines, or edges meet
*Vertex (computer graphics), a data structure that describes the position ...

interaction point
In particle physics, an interaction point (IP) is the place where particles collide in an accelerator experiment. The ''nominal'' interaction point is the design position, which may differ from the ''real'' or ''physics'' interaction point, where ...

particle accelerator), whose study is the ultimate goal of the experiment, can be determined. The total event reconstruction is not always possible and necessary; in some cases, only a part of the data described above is obtained and processed.
