The LHC Early Phase for the ILC Working Groups |

Working Group II

WG I: Only one state, SM-like
Higgs boson, at the early stage of LHC The charge of the working groups focussing on LHC / ILC interplay at the LHC early phase
for the ILC workshop is to investigate various possible scenarios of early
LHC data. For the purpose of this workshop "early LHC data" should
be understood as an integrated luminosity of about 10 fb-1.
In particular, the following questions should be addressed:
These questions should be
investigated within the following classes of possible scenarios of results
observed in the initial LHC runs:
a)
The
detection of only one state with properties that are compatible with those of
a Higgs boson;
b)
No
experimental evidence for a Higgs boson at the early stage of LHC
c)
The
detection of new states of physics beyond the Standard Model
In analysing these scenarios, the
working groups should clearly distinguish between assumed experimental
signatures and their possible interpretations within certain models. Possible
theoretical uncertainties should be carefully investigated.
i)
Missing
energy (+ nothing, leptons, jets) signals
ii)
Leptonic resonances
iii)
Multi-Gauge-Boson
signals
iv)
Everything
else.
The convenors will include one LHC experimentalist, one ILC experimentalist and one or two
theorists for each group. Each group should identify the most promising
physics channels for the class of events they are studying and have both
detector as well as beam diagnostic experts as part of their working group.
The precision with which event and
machine parameters can be measured needs to be convoluted with the
anticipated signals to obtain meaningful ILC-LHC case studies in a uniform
framework. The physics studies should identify the detector and machine
specifications one needs to reach the physics goals. Where possible, the
sensitivity of each process to critical detector and machine parameters ought
to be studied.
