DESCRIPTION:*Speaker : Prof. Eun-Suk Seo (University of Maryland) [home]\
 n\n*Abstract : One of the most exciting possibilities in cosmic ray resea
 rch is the potential to discover new phenomena. Elementary particles were 
 discovered in cosmic rays before modern-day accelerators became available 
 to study their detailed properties.  Since the discovery of cosmic ray an
 tiprotons in 1979 using a balloon-borne magnet spectrometer\, a series of 
 magnet spectrometers have been flown to search for the signature of dark m
 atter annihilation in antiprotons and positrons. Being the same as particl
 es except for their opposite charge sign\, antiparticles are readily disti
 nguished as they bend in opposite directions in the magnetic field. As lon
 g-duration balloon flights over Antarctica became available\, not only ant
 iproton to proton ratios\, but also measurements of antiproton energy spec
 tra became possible. Furthermore\, PAMELA on a Russian Satellite and AMS-0
 2 on the International Space Station (ISS) are currently providing precisi
 on measurements of various particles and anti-particles\, including positi
 ons and antiprotons. In particular\, excess positrons generated a lot of e
 xcitement due to their possible explanation of dark matter. More recently\
 , the JAXA-led CALET ISS mission and the DAMPE Chinese Satellite were laun
 ched. NASA’s ISS-CREAM was delivered to KSC to await launch by SpaceX af
 ter completing its final verification at GSFC. These missions will provide
  complementary measurements exploring energies higher than previously poss
 ible to constrain cosmic ray propagation models in search of dark matter a
 nd the origin of cosmic rays. Recent results\, their implications\, and th
 e outlook for the field will be presented.\n\n \n\nhttps://sshep.snu.ac.k
