For Glauber-type initial conditions, while data on integrated v_2 is consistent with a ratio of viscosity over entropy density up to eta/s=0.16, data on minimum bias v_2 seems to favor a much smaller viscosity over entropy ratio, below the bound from the AdS/CFT conjecture. Some caveats on this result are discussed.","external_url":"https://arxiv.org/abs/0706.1522","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-07-04T06:09:37.028348+00:00","pith_arxiv_id":"0706.1522","created_at":"2026-05-10T22:20:47.143461+00:00","updated_at":"2026-07-04T06:09:37.028348+00:00","title_quality_ok":true,"display_title":"Viscosity Information from Relativistic Nuclear Collisions: How Perfect is the Fluid Observed at RHIC?","render_title":"Viscosity Information from Relativistic Nuclear Collisions: How Perfect is the Fluid Observed at RHIC?"},"hub":{"state":{"work_id":"36f5832b-b40e-456d-b1d8-2b94ede44ca9","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":14,"external_cited_by_count":null,"distinct_field_count":5,"first_pith_cited_at":"2019-07-12T18:55:09+00:00","last_pith_cited_at":"2026-06-30T14:40:14+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-08-05T02:34:31.312296+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":1}],"polarity_counts":[{"context_polarity":"background","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
