{"id":"https://openalex.org/G8099788900","display_name":"Cosmological tests of  charged supersymmetric particles","description":"During the period in which I have been supported by this grant, I have published 34 papers including a single concluding full-length paper. In response to the discovery of the Higgs particle in 2013, the parameter spaces of Minimal  Supersymmetric Standard Models (MSSM) have been restricted severely. In order to fit the data of the relicabundance of the cold dark matter which could be a particle in MSSM, and satisfy the conditions for the successful big-bang nucleosynthesis, the allowed parameter spaces have been severely shrunk or disappeared. However, we have shown that if we add a new singlet particle (singlino) into the MSSM model, the situation is changed. The singlino can become the cold dark matter, and the existence of the long-lived scalar tau lepton can solve both the Lithium 7 and Lithium 6 problems simultaneously in some parameterspaces. By those achievements, we have summarized all of known important effects on cosmology  induced by a long-lived charged massive particle.","funder_award_id":"23540327","funder":{"id":"https://openalex.org/F4320334764","display_name":"Japan Society for the Promotion of Science","doi":"10.13039/501100001691"},"funded_outputs":["https://openalex.org/W1502381725","https://openalex.org/W1969682371","https://openalex.org/W1976662507","https://openalex.org/W1988702645","https://openalex.org/W1999191847","https://openalex.org/W2001891705","https://openalex.org/W2007017782","https://openalex.org/W2011271215","https://openalex.org/W2044062824","https://openalex.org/W2046186892","https://openalex.org/W2051058032","https://openalex.org/W2052342887","https://openalex.org/W2063173620","https://openalex.org/W2065631160","https://openalex.org/W2083666825","https://openalex.org/W2088771376","https://openalex.org/W2092375032","https://openalex.org/W2123628367","https://openalex.org/W2125596142","https://openalex.org/W2128960110","https://openalex.org/W2134463234","https://openalex.org/W2136991005","https://openalex.org/W2143898379","https://openalex.org/W2147427182","https://openalex.org/W2156421339","https://openalex.org/W2159350339","https://openalex.org/W2166022723","https://openalex.org/W2168511624","https://openalex.org/W2949733558","https://openalex.org/W2950640299"],"funded_outputs_count":30,"parent_awards":[],"sub_awards":[],"sub_awards_count":0,"amount":5200000.0,"currency":"JPY","amount_usd":63593.29,"amount_usd_basis":"daily_rate","recipients":[],"recipient_countries":[],"recipient_regions":[],"research_scope":{"is_research":true,"basis":"funder_default","tier":1},"funding_type":"research","funder_scheme":"Grant-in-Aid for Scientific Research (C)","start_date":"2011-04-28","end_date":"2015-03-31","start_year":2011,"end_year":2015,"landing_page_url":"https://kaken.nii.ac.jp/en/grant/KAKENHI-PROJECT-23540327/","doi":null,"provenance":"kaken","lead_investigator":{"given_name":"Kazunori","family_name":"KOHRI","orcid":null,"role_start":null,"affiliation":{"name":"High Energy Accelerator Research Organization","country":"Japan","ids":[{"id":"https://nrid.nii.ac.jp/nrid/1000050565819","type":"nrid","asserted_by":"kaken"}]},"author":{"id":"https://openalex.org/A5016484890","display_name":"Kazunori Kohri","orcid":"https://orcid.org/0000-0003-3764-8612"},"institutions":[{"id":"https://openalex.org/I138728355","display_name":"High Energy Accelerator Research Organization","ror":"https://ror.org/01g5y5k24","country_code":"JP","type":"facility","lineage":["https://openalex.org/I1319490839","https://openalex.org/I138728355"]}]},"co_lead_investigator":null,"investigators":null,"works_api_url":"https://api.openalex.org/works?filter=awards.id:G8099788900","primary_topic":{"id":"https://openalex.org/T10048","display_name":"Particle physics theoretical and experimental studies","score":0.7052,"subfield":{"id":"https://openalex.org/subfields/3106","display_name":"Nuclear and High Energy Physics"},"field":{"id":"https://openalex.org/fields/31","display_name":"Physics and Astronomy"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"}},"topics":[{"id":"https://openalex.org/T10048","display_name":"Particle physics theoretical and experimental studies","score":0.7052,"subfield":{"id":"https://openalex.org/subfields/3106","display_name":"Nuclear and High Energy Physics"},"field":{"id":"https://openalex.org/fields/31","display_name":"Physics and Astronomy"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"}}],"institution_awarded":[{"id":"https://openalex.org/I138728355","display_name":"High Energy Accelerator Research Organization","ror":"https://ror.org/01g5y5k24","country_code":"JP","type":"facility","lineage":["https://openalex.org/I1319490839","https://openalex.org/I138728355"]}],"updated_date":"2026-11-11T03:01:08.000Z","created_date":"2026-07-13T04:17:19.000Z"}
