+ | **EWinos** | ||
+ | |||
+ | * Proposal to study pp-> chi2,chi3 -> gamma l^+ l^- chi1 chi1. Signal with low MET if chi1 much lighter than nearly degenerate chi2,chi3. | ||
+ | * Higgs to electroweakino => in Higgs group [[2015:groups:higgs:morehiggs:hxx|Higgs to electroweakino]] | ||
+ | * EWinos decays to other (light) Higgses e.g. in NMSSM => cross-section too small if decays into Higgs. Is there anything not covered by 2HDM Higgs searches? Daniele Barducci, Genevieve Belanger, Dipan Sengupta | ||
+ | |||
+ | **Compressed spectra** | ||
+ | |||
+ | * Analyse the decay squark -> q lepton + RH sneutrino in a regime where the squark, sneutrino splitting is small (as arises in some Pati-Salam type of GUTs). Basic question: How large the splitting must be for the signal to be visible at the LHC? __Leader__: Werner Porod, __other members__:??? | ||
+ | * What prospectfo ISR tagging? | ||
+ | * Studying dilepton invariant mass distribution below 20GeV might be needed if compressed spectra. __Leader__: ???, __other members__:??? | ||
+ | |||
+ | **Stops** | ||
+ | * Is light stop totally excluded in the MSSM? __Leader__:Giacomo P. __other members__:??? Two holes hard to analyse: 1) stop close in mass with LSP+top, in a regime where top cross-section measurements doesn't help. 2) stop -> b chargino in a regime where W is off-shell. | ||
+ | |||
+ | * Which Higgs mass tool to trust in a regime where stops are around 1TeV. Spheno,softSUSY,suspect VS. FeynHiggs VS. SUSYHD. | ||
