ISS and NuFact
Major effort to consider status of this project
The ISS:
• Initiated at NuFact05, concluded at NuFact06:– Report now in preparation
• Goals:– Critical comparison of the performance of the three options– Establish a baseline for the accelerator and detector systems
requiredi.e. lay the foundations for a detailed International Design study leading to conceptual design report(s)
• Work of ISS carried out in three working groups:– Physics (convener Y. Nagashima, Osaka)– Accelerator (convener M. Zisman, LBNL)– Detector (convener A. Blondel, Geneva)– Overall coordination via Programme Committee chaired by P.

The International Scoping Studyof a future Neutrino Factory and super-beam facility
Two main physics strategies
use of the high neutrino rate (>1020/year) and energy (10-50 GeV) of Neutrino Factory + LMD (“Super-MINOS”) detector of large but not huge mass (50-100 Kt), necessarily magnetic (a dense magnetized Iron detector, or, possibly, Li-Argon, TASD), a few 1000 Km away.

ctroweak Symmetry Breaking
What is E-W symmetry breakingWhat are the known knowns?What are the known unknowns?What about the unknown unknowns?
W.Murray PPD 42
9 years ago..
“The LHC would certain-
ly ferret out the Higgs by
2007”
W.Murray PPD 43
What is E-W symmetry breaking?
This gauge symmetry predicts γ,W,Z,gluons Requires them to be massless
Symmetry breaking is needed for W/Z masses
SU(3) x SU(2) x U(1)
W.Murray PPD 44
How can it occur?
Preserver underlying symmetrySpontaneous or dynamical breakingPreserves ρ=1
(Relative strength of neutral and charged current interactions)
Higgs mechanism!
Dr Bhattacharyya will cover this in detail.
W.Murray PPD 45
Two experimental themes
Precision Electroweak dataIs ρ=1 true?Are the loop effects correctly seen?Can we predict the Higgs mass from them?Needs masses, couplings...
Direct Higgs searchWhat can we say about SM HiggsWhat does the future hold? And when?What about Super-symmetry?

Fermio-phobic HiggsD0, 0.83fb-1
No sign of signalExclude fermio-phobic Higgs below 66GeV if H+ mass 100GeV

LHC expectations:
H/A similar shape to TeVatronBut hugely expandedHH can be found for most of plot
But not all CPV scenarios all Higgs may escape
W.Murray PPD 100
Conclusions
Incredible new results from Tevatronm
W precision improving
Higgs mass below 150GeV seems clearDirect Higgs searches close to sensitive
LHC will start this yearThere is a real race happening
Do NOTNOT assume the unknown is trueBut in 2010 electroweak symmetry breaking of the SM will be established – or clearly wrong
A lepton collider will be required to explore properties
