What we needs for Dark Matter 25

From Experiment  Person Power:  Dedicated team/scientists for DM search for HW/SW  Networking  Networking for both Korea experimentalists in local and international institutions in DM search experiments (in Indirect, Direct and Colliders)  Regular workshop including international workshop  Enhancement communication between experimental and theoretical community ⇒ brain-storming to new ideas  Computing resources for big data :  HPC (High-Performance Computing) for MC  Storage for experimental data and theoretical model 26 Prof. H.D. Yoo. Y. Kwon

From Theory  Rapid update & sharing of information  Key point summary DB site by specialists  Regular meeting, Network Feedback between experimentalists and theorists ⇒ Through a (new) center  Rapid & Easy comparing check of theoretical model  Development of new numerical package  Computing power and Person power ⇒ new jobs  Cross check with astrophysics (theoretical model)  N- body simulation  Discussion with DE survey group 27 Prof. J.C. Park

Suggestions  Model DB and Simulation Parameter  To develop DM System based on computational Science  Experimental results supports to constrain parameters of theory.  Theories enhance the accuracy of expected values.  Automated tools (computing+ manpower) supports rapid and accurate results  The development of S/W  To support various measurements in Indirect, Direct and Collider 28 Prof. S.C. Park Dark Matter Research Management System

Schedule  Dark Matter Workshop  KISTI, Daejeon  Report  Current Status of Dark Matter  Proposal  NST, MISP, etc.
