2 PPC Projects Experiment-Theory (ET) Collaboration Develop technique(s) a) To extract key final states; b) To measure SUSY masses in a minimal framework; c) To determine model parameters; d) To extract Ω (amount of the dark matter) at the LHC; Ω SUSY Ω DM e) To expand to non-minimal scenarios; f) To expand to non-susy scenarios (e.g., UED); and carry out at ATLAS and CMS! 2

4 Probe Metric at the LHC We test msugra cases first, followed by a non-universal SUGRA case. Minimal SUGRA E LHC Future Collider Ω 2 ~ 0h A χ 1 = D ( m0, m1/2,tanβ, 0 ) 1 Non-Universal SUGRA Tevatron 2 Ω ~ 0h = D m, m,tanβ, A, µ ) 1 χ ( 0 1/2 0 2 Precision 4
5 BEST Part 1 : Why? Our studies have been based on msugra. 1 However, when we extend it to nonminimal scenarios, we see a case where W s become a key to reconstruct the SUSY masses. 2 We want to reconstruct W jj in all hadronic mode of SUSY events 5
6 Non-Universal SUGRA Dutta, Kamon, Kolev, Krislock, Oh Phys. Rev. D 82 (2010) [arxi: ] msugra: Unified masses at the GUT scale Parameters : m 0, m 1/2, A 0, tanβ, sign(μ) (*) Good enough to confirm that the dark matter is the SUSY weakly interacting neutral particle. nusugra: Unified masses at the GUT scale, except Higgs Parameters : m 0, m 1/2, A 0, tanβ, μ(m H ) (*) small μ makes neutralino Higgs-like annihilation cross section is large enough to have right amount of dark matter today. [Q] Is a cosmological measurement possible for non-minimal case? 6
