Description
An indirect measurement of the antiproton flux in cosmic rays is possible as the particles undergo
deflection by the geomagnetic field. This effect can be measured by studying the deficit in the flux,
or shadow, created by the Moon as it absorbs cosmic rays that are headed towards the Earth. The
shadow is displaced from the actual position of the Moon due to geomagnetic deflection, which is a
function of the energy and charge of the cosmic rays. The displacement provides a natural tool for
momentum/charge discrimination that can be used to study the composition of cosmic rays.I will use the data from the LHAASO-WCDA experiment to measure the ratio of positrons to antiprotons in the future.
Dark matter is a highly significant and fascinating subject in the field of new physics. LHAASO is expected to serve as a powerful tool for indirect detection of dark matter. In the future, WCDA will join this collaborative group, and I will participate in the data analysis of WCDA. It is anticipated that the inclusion of WCDA will provide results in the lower energy range and offer more comprehensive findings.
