Concluding Remarks Dongchul Son Center for High Energy Physics Kyungpook National University

Examples of Leading Questions National Research Council Committee on Physics of the Universe report 1. What is dark matter? 2. What is dark energy? 3. How were the heavy elements from iron to uranium made? 4. Do neutrinos have mass? 5. Where do ultra-energy particles come from? 6. Is a new theory of light and matter needed to explain what happens at very high energies and temperatures? 7. Are there new states of matter at ultrahigh temperatures and densities? (Quark-Gluon Plasma State) 8. Are protons unstable? 9. What is gravity? 10. Are there additional dimensions? 11. How did the Universe begin?

ILC, the Door to a Scientific Revolution Findings in the past years still lead us to many leading questions (suggesting low SM higgs mass, TeV Scale Physics, possibly with SUSY, dark matter, dark energy, extra dimensions, etc.) While we have many remarkable theoretical models, we need more comprehensive understanding of what we observe We need the experimental tools now or in the near future to make the discoveries In 2007 LHC will turn on. With its great discovery potential, the LHC probably lay the foundation of our understanding The LHC alone will not suffice to unlock all the mysteries. ILC will take additional tools to make the complementary discoveries needed to sharply and fully understand our Universe

ILC: the Energy Frontier Machine

Enormous Strides toward ILC The HEP community has made enormous strides this past year, both in the accelerator and detector arenas, towards realizing a unified, international design for the ILC –ICFA (with ACFA, ECFA, US) established ILCSC in 2002 –We have a Very Active ILCSC Concepts of GDE/GDI/Organization LC Parameters (Sep 2003) Cold Technology (ITRP, Aug 2004) 1 st ILC Workshop (Nov. 2004) GDE Director (Feb, 2005)

Global Design Effort (GDE) On March 18, 2005 Barry Barish officially accepted the position at the opening of LCWS 05 meeting at Stanford Barry reported the GDE plan at this ACFA workshop Now we also have a new ILCSC Chair, Prof. Sin- ichi Kurokawa. Congratulations !

From Governments and Funding Agencies side OECD – Global Science Forum launched th Consultative Group on HEP and accepted its report on HEP Roadmap, etc. (2002) OECD Ministerial Meeting (Jan 2004) adopted statements on LC as a next collider machine, emphasizing the importance of global R/D efforts, manpower raising-up, and early discussions among government agencies Funding Agencies for LC(FALC) meetings began 2003 and started discussion on MoU and Site Selection –Asia partners (Japan, Korea, India) joined (2004) –FALC established FALC-Resource Group (Feb. 2005) Expect More Activities in coming years

GDE Director’s View and Plan Near Term Plan –Staff the GDE Total staff size about 20 FTE ( ) –Organize the ILC effort globally First Step --- Appoint Regional Directors within the GDE, Make Website, coordinate meetings, coordinate R&D programs, etc –R&D Program Coordinate worldwide R & D efforts, (Proposal Driven to GDE) Technically Driven Schedule

Near Term Plan (GDE) Schedule Begin to define Configuration (Aug 05) Baseline Configuration Document by end of Put Baseline under Configuration Control (Jan 06) Develop Reference Design Report by end of 2006 Three volumes -- 1) Reference Design Report; 2) Shorter glossy version for non-experts and policy makers ; 3) Detector Concept Report

The Machine Accelerator baseline configuration will be determined and documented (BCD) by the end of 2005 R&D program and priorities determined (proposal driven) Baseline configuration will be the basis of a reference design done in 2006 The Detector(s) Determine features, scope: one vs two, etc (same time scale) Measure performance of the baseline design Beam delivery system and machine detector interfaces Define and motivate the future detector R&D program The GDE Plan

Now, ILC on its Vehicle The results of studies presented and summarized at this workshop will provide very sound inputs to the Global Design Efforts (especially to the 2 nd ILC Workshop and Snowmass) This workshop also had discussions on accelerator / Machine Detector Interface (MDI) issues (new approach and very productive) GDE Director wants Detector/Physics staff in Central/Regional Teams Welcome this kind of very cohesive approach to ILC Design

ILC, a New Truly Global Project / Lab It is very important that not only the ILC efforts but also a (existing or new) Lab hosting ILC should be truly GLOBAL and INTERNATIONAL in order for the ILC to be realized TIMELY and SUCCESSFULLY So is the G(lobal) D(esign) E(fforts) The Regional Efforts within Asia should be truly multi- laterally international To be so, it is highly desirable to keep this spirit among us and to show it to public during the courses of efforts even though there are a very big gaps and differences in the levels of understanding and supports and wide range of rationale among Asian countries Nevertheless, we should NOT forget that ILC physics to be pursued should be emphasized with the highest priority among us and to the public

Messages from OC and Others

Plan of Activities in Asia Let us make an MOU among Asian institutes and interested parties (for a realistic level, starting from groups in University, labs, etc) Regarding regional activities for general aspects for ILC including physics and detector R&D, accelerator R&D and outreach to various societies and bodies. This will be a basis to secure R&D budgets from many resources and governments. Based on discussion among members of ACFA, ALCSC, ICFA, Asian Regional Team, and ACFA LC Workshop OC

Continue regular meeting among Asian members of ACFA, ALCSC, ICFA, Regional team headquarters, ACFA OC. A teleconference meeting before Snowmass, then a face-to-face meeting at Snowmass. Urgent tasks 1.A very urgent task is to identify active contact persons (3-4?) and outreach experts in each country. 2.An important target is to form the MOU above. 3.Draft to propose structure of regional GDE. 4.Draft to propose (request) what role, what to do, authority of regional director. Long term— 5.Seek ways to get budgets and expand outreach.

Outreach group First task: GLC executive summary  translate to each local language. Title GLC  ILC Translation of web page made by GDE. 1-2 page pamphlet. An idea To Organize `Council` consisting of High level persons, discuss founding/human resource advice regional team, ACFA, Contact governments together with GDE, regional GDE, ALCSC, ACFA. Next ACFA workshop China or Japan. Avoid too many meeting, but regional meetings are important. Hopefully to be decided by the time of Snowmass meeting.

The next ACFA LCWS 1 st 1998 Beijing 2 nd 1999 Seoul 3 rd 2000 Taipei 4 th 2001 Beijing 5 th 2002 Tokyo 6 th 2003 Mumbai 7 th 2004 Taipei 8 th 2005 Korea  This workshop 9 th 2006 Japan or China

Advertisements Don’t forget coming events!!! –8 th ICFA Seminar 28 September ~ 1 October, 2005 Kyungpook NU, Daegu, Korea ILCSC (27 Sep), ICFA (29 Sep), FALC RG Meetings (1~2 Oct morning) will be co-located ACFA Plenery Meeting (2 Oct) at Pohang –LCWS ~14 March, 2006 Bangalore, India GDE Meeting will be co-located
