Reconstruction methods in high energy physics experiments

High energy physics is a study of the most fundamental (tiniest?) building
blocks of nature and the laws that govern their interactions. A lot of our
current understandings about the universe have been achieved by observing
these interactions in different high energy physics experiments. In past
50-60 years, there has been a very rapid development in the detection
technologies of these experiments. The signals observed in these detector
systems contain new physics information in the form of currents and
voltages. In order to understand the hidden physics, one must separate the
signals generated from genuine events from the backgrounds, identify the
vertices of interactions, identify the final state particles and measure
their charge, momenta, directions etc. These are commonly referred to as
the reconstruction methods. In this talk, a general overview of these
topics will be given.
