…

The Committee suggests that the government of Japan should

(1)secure the budget required for the investigation of various issues to determine the possibility of hosting the ILC, and

(2)conduct intensive studies and discussions among stakeholders, including authorities from outside high-energy physics as well as the government bodies involved for the next two to three years.

...

In parallel, it is necessary to have discussions with the research institutes and the responsible funding authorities of key countries and regions involved outside of Japan, and to obtain clear understanding of the expected sharing of the financial burden.

 (Draft) Report to the Academic Experts Committee Regarding the International Linear Collider (ILC) : Outline

The Particle and Nuclear Physics Working Group: (submitted to “MEXT Academic Expert Committee for ILC held on 21 April, 2015) Personally Translated by K. Fujii and edited by A.Yamamoto, 6 April, 2015  1. Scientific Significance (Role of ILC Concerning the Future Perspectives of Particle Physics ) ○History and current status of elementary particle physics:

　・ Elementary particle physics has been making a great progress along with 　　　　 advances of particle accelerators, in recent years, with that of colliding 　　　 accelerators in particular. 　・ By the end of the 20th century the correctness of the Standard Model of 　　　 particle physics had turned out to be quite solid.　・ In 2012, the Higgs boson that gives masses to elementary particles was 　　　　 discovered. 　・ It has also been widely recognized that the Standard Model would not be the　　 ultimate theory.　・ The mainstream of particle physics is now shifting to the quest for physics 　　　 beyond the Standard Model.

9

○The International Linear Collider (ILC) is a facility to do experiments and 　　　　　 searches concerning the following items:　① Full elucidation of the Higgs boson properties and precision studies of 　　　　 the top quark　② Searches for new particles (such as super-symmetric particles)　③ Others (such as dark matter and extra dimensions)

○There are significant scientific meanings as targets of future elementary 　　　　　 particle physics to study the items listed above.

2. Cost (Excerpt from the TDR validation WG report)○The accelerator and the tunnels to house it: about 8,300 x 108 JYen.　 (In addition, costs for the detectors to observe collision events and labor 　　 for construction, etc. will be needed.)

○Total cost for the construction of the accelerator facility: about 1.1 x 1012 　　　　 JYen (including labor).

○Running cost: about 400 x 108 JYen/year.

○The cost is to be internationally shared.

10

3. Past examples of construction costs in accelerator facility implementations ①Examples in Japan J-PARC 　　　　　　　　　　　 <<omit details>> 　　　　　　　　・②Examples overseas LHC at CERN 　　　　　　　 <<omit details>> 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 There was a prospect for the Higgs discovery at the time of the construction 　　 start based on the experimental data available by that time and the standard 　　　 model assumption. However, the discovery would have been made by some 　　　 other experiment before the LHC. 4. Experiments that ILC will be able to carry out as described in the TDR・ The next target of elementary particle physics is to discover “new phenomena 　　 beyond the Standard Model”. The ILC will enable the following:・ Searches for physics beyond the Standard Model through precision 　 measurements of the Higgs boson and the top quark.・ Searches for supersymmetric (SUSY) particles (Note that the LHC after its 　 energy-upgrade will also search for strongly interacting SUSY particles 　 (mainly in 2015~2017)).・ Searches for dark matter particles and extra dimensions etc. 

11

5. View points for judging if the scientific case is matching the investment

○The optimal strategic prospects for research should be clarified based on 　　　　 the results of searches for strongly interacting SUSY particles, etc. at the 　　 13TeV LHC.

○In order to carry out the research program according to the optimal 　　 strategic prospects, it is necessary to reassess the appropriateness of the 　　 performance described in the ILC TDR.

○Since the ILC is an international project that requires the enormous cost, 　　 significant international cost sharing should be prerequisite, considering 　　 the budgetary situation in Japan.

○Considering the scale of the necessary investment for the ILC project, it is 　　　 important to get understanding and cooperation from communities of other fields.

○In case timely decision should not be made concerning the ILC project 　　　　 implementation, the project might lose its international appeal. It is hence 　　 important to formulate a system so as not to delay the decision. 

6. Scenarios at the ILC based on anticipated achievements at the 13TeV LHC(1)In the case of discovery of a new particle (which appears to be consistent with SUSY):•Strategy: Using the ILC, elucidate new physics phenomena behind the new particle through precision measurements of the Higgs boson, etc. If the ILC energy is sufficient, discovery of some other new particles linked to the LHC discovery is anticipated.

(2) In the case of observation (or discovery) of events hinting at a new phenomenon (dark matter, etc.) other than the above:•Strategy: Scrutinize the new phenomenon discovered at the LHC.

(3) In the case of no discovery of any new particle or phenomenon at the 13TeV LHC:•Strategy: Search for physics beyond the standard model through precision measurements of the Higgs boson, etc. Search also for new particles that are difficult to find at the LHC. Investigate in detail possible reason for the non-discovery at the 13TeV LHC and examine whether energy upgrade would be necessary in the future or not.

Outline of the Status Report of ILC-TDR Verification WG

reported to the 2nd MEXT ILC “Academic Expert” Committee, on 14 November, 2014

1. ILC Cost Estimate Summary in TDR converted to JYen

1)Acc. constr. (material) : 8,309 Oku-Yen (Labor) : 22.892 M person-hrs ( ~ 1,600 Oku-Yen)

2)Det. Constr. (material): 766 Oku-Yen (Labor) : 2,148-person-yrs ( ~ 240 Oku-Yen)

3)Exclusive in TDR : preparation budget, living environment, land acquisition, access road, life-line infra-structure, computing center etc.

4)Uncertainty: ~ 25 %

5)Annual operational cost in TDR; 491 Oku-Yen

Continued2. Technical Issues and Cost Risks in TDR

1)Risks in the cost estimates remaining with; – Insufficient margin in cost because of the current achievement basis. – Possible cost increase caused by unexpected happening, and of less

sufficient study on human resources required,

2)Technical reality/feasibility– Less design margin, with assuming the performance, based on the past

research achievement to be realized in the project. – No demonstration yet of a sufficiently large scale system – Reproducibility of the component performance, in case that multiple

vendors be distributed, worldwide

3)Human resource for construction, operation, and management – Necessary reliable plan for human resource for the ILC construction– Study of management for contract and system assembly etc.

3. Points to be considered in further process

1)International Cooperation– Consensus/agreement for safety and legal regulation

2)Others needed to:– Consider available budget limitation in our country. – Watch the various constraints in each country– Maximize feedback from the R&D progress for further

improvement of the accelerator performance.
