Περίληψη:
We attempt the derivation of a new coupling function between ground
level and primary cosmic rays for the case of Forbush decreases. The
calculations for the new function are based on basic Quantum Field
Theory theoretical tools, something that has not been attempted till now
in other widely used cosmic ray coupling functions. The use of Quantum
Field Theory calculations in cosmic rays events in general, is expected
to be a suitable frame of work since it describes well the high energy
particle interactions which result in variations to the total number of
the particles involved through annihilation or creation of particles.
The newly computed function is tested to the case of two events of
Forbush decreases, February 2011 and March 2012, using data from the
high resolution neutron monitor database. Results for the primary
particle intensity values obtained from this function are compared
directly to the corresponding ones from the use of the Dorman's widely
accepted coupling function. The two sets are discussed in detail in
order to deduce the possible suitability of Quantum Field Theory tools
to cosmic ray events.
