LHC - SM Higgs
The LHC detectors are designed to find the SM
Higgs. Low mass is covered by ??, ttH(bb),
qqH(WW,??). A low mass Higgs has many
accessible decay modes ? couplings measured.
4
LHC - SUSY
Energy matters! One month at 1/10 design
luminosity extends mass reach by a lot. LHC
experiments must be ready on week one for new
Physics.

Project Financial Summary
55 months of reporting. Note BA in FY06 (4.2 M)
and FY07 (1.3 M). CD4-a, CD4-b
31
US CMS Detector Project
Contingency will be applied to scope if it is
earned. We hope next to apply scope to ECAL (1.7
M) and perhaps then increase scope to cover some
of CMS LV (lt1.5 M). Yarema, Beverly and Huffman
(FNAL EDIA) are estimating costs for the latter.
32
Tracking Closely
We retain 49 contingency, or 19.12 M on our
ETC. The Project is 74 complete. It is crucial
not to be fooled. To that end, we brought NSF
tracking up to date (MRE end). We have also seen
other late charges items we announced were
closed and complete. A soft landing will be
hard to accomplish. It is getting harder as time
goes on.

Project Complete -gt MO
MO begins with commissioning and preops in SX5
in FY03. Aim to end Project in FY05, with
completion in FY08 UX5 installation.
36
Endgame and CD4
The US CMS deliverables will be 96 complete in
FY05 and finally installed in UX5 by FY07. The BA
has evolved to reflect this fact. Thanks to DOE
for adjusting CD4.
37
Scrubbed MO
Added Tier-2 support (NSF) in Physics Analysis
centers. We would like to do more to support US
physicists doing analysis at their home
institutes or at a local PAC. There will be an
external review on April 8-10 of MO.
38
US CMS MO Resources
Note the rolloff of construction to MO by FY05.
The major category for MO is physicists -gt base
program.
BaBar Reality check
39
ML for RP V33
Tie points from Computing Systems DC Physics
TDR VCRs and PACs. The RP is a unitary plan to
do Physics in the U.S.
40
CMS and the PRS Groups
The PRS groups are part of the detector groups
and part of the Physics Subsystem. The plan is to
tie Physics analysis to the detector builders and
to the analysis teams.
41
Jet, MET Group and Physics TDR
Need to decide on a few Physics processes to
explore in depth for the Physics TDR qqH(WW),
SUSY ?? Then seed the Data Challenge data with
events from these reactions.
42
G4 and Test Beam
The Jet/Met group is involved in analysis and
simulation of the test beam data
43
LHC Physics in the US
In US CMS, planning is in place for a
collaboratory or virtual laboratory. Elements
are Virtual Control Room (commissioning, shifts)
and Physics Analysis Centers ( teleconf, analysis
groups). This support will go directly and solely
to US HEP physicists.
44

51
Resource Expectations for Data Challenge 04
52
Bare Bones Plan Top-Down

• As a response to the revised funding guidance
  defined a Bare Bones project plan
• Continue to deliver SC engineering support to
  CCSkeep this effort constant over the next 2
  years, instead of ramping further
• However, CMS Software is about 12 months behind
  due to past severe understaffing
• CMS needs the US (and CERN etc) man power to work
  with the LCG Applications Area,
• Contingencies if any will possibly develop in
  course of joining forces with ATLAS et al
• Ensure the US CMS system of Regional Centers is
  ready for the Data Challenges(finally!) ramp the
  Tier-1 effort to the required level of 13 FTE in
  FY2003
• Starting at 6 FTE now, need to ramp to 13 FTE to
  fully participate in the Data Challenges
• The Bare Bones plan should enable US CMSto
  become part in the LCG Production Grid
  milestone during 2003
• Can participate in DC04 and 10 Data Challenges,
  will try to pull in as much as we can from Grid
  projects
• Modest hardware procurements for Tier-1 and
  Tier-2 centers
• Typically 500k/year in FY2003, FY2004
• Need more (700k) in 2005 (latest) for
  participation in 10 challenge, RC TDR
• Start the deployment phase late in 2005
• Then need to start hiring or re-assigning
  facility support people at the Tier-1
• Start pilot implementation of US Tier-2

53
Conclusions on US CMS SWC

• US CMS SC Project is delivering a working Grid
  environment, with a strong participation of
  Fermilab and U.S. Universities
• We need to do a lot more RD to build the system
  for physics
• Our customers (CCS, PRS and US CMS Users) are
  happy (last time we were asking), but need and
  want more support
• US CMS is driving the US Grid integration and
  deployment work
• We have a unique opportunity to bring in our
  ideas of doing science in a global and open
  international and collaborative environment
• Proposal to the NSF ITR solicitation to Globally
  Enable Analysis Communities
• That goes beyond the LHC and even HEP
• US CMS has shown that the US Tier-1/Tier-2 User
  Facility system can indeed work to deliver
  effort and resources to US CMS!
• We definitely are on the map for LHC computing
  and the LCG
• With the funding advised by the funding agencies
  and project oversightwe will have the manpower
  and equipment at the lab and universities to
  participate in strongly in the CMS data
  challenges,
• bringing the opportunity for U.S. leadership into
  the emerging LHC physics program

54
US LHC and the RP
US CMS has made a survey of intent. It appears US
CMS will grow by a factor 2 by FY07. In
addition, new groups will join before first
beam. We would like to have the flexibility to
plan for these additional physicists.
55
Cost Estimates for the RP
The US CMS community has carefully estimated and
scrubbed the costs for the Research Program. The
US CMS community estimates that more support is
needed in FY07 and beyond. Present planning
within the guidance provided in the Budget
Authority delays RD for upgrades, slows the SWC
ramp up (bare bones), and reduces the contingency
fund to a level which limits management agility.
56
Research Program - BA
NSF has given new guidance. Starting in FY03, the
NSF plan is to ramp to 12.5 M for US CMS in 5
steps of 2.5 M each. New DOE guidance helps 04
and 05. The scrubbed MO and bare bones SWC is
still tight in FY03. In FY04 we might be able to
increase SWC, add Tier 2 PAC support, etc.
57
NSF MRE -gt Ops !
This is a great accomplishment and the investment
of NSF in the future shows confidence.

59
Issues

• The ramp up of the RP is crucial. FY03 and FY04
  will either get us a good start on preparation
  for Physics or we will drop the ball on Data
  Challenges and the Physics TDR.
• A firm commitment by NSF and DOE is absolutely
  necessary if we are to plan rationally. The MO
  Evaluation Group and SWC Reviews is a start.

60
Summary

• US CMS is on schedule and on budget for the
  Detector Construction.
• CERN and CMS appear to be holding schedule. Beam
  in 2007 with luminosity 1/10 design is quite
  thinkable.
• For the RP, CD4 is altered, BA is known up to
  increments. The ML use the CMS schedule. Start
  FY02 tracking of the RP under SOW agreements for
  MO and SWC. The RP has been (over)scrubbed.
• A cornucopia of Physics awaits us and we need to
  be ready for the harvest.

LHC Physics - Priority
HEPAP Subpanel on Long Range Planning Report puts
a high priority on the Physics of the LHC (all
quotes in this talk are from the Subpanel Report).
62
LHC Computing Grids
The IT tools developed for LHC physics analysis
are and will be vital to the advancement of
global science. Grid computing will make a major
impact in many areas of business and commerce.
The leading role of LHC was recognized in the
HEPAP Subpanel Report.

72
Research Program - Upgrades
HEPAP Subpanel Report gives strong support to LHC
Upgrades. The present Budget Authority makes
strong Upgrade RD impossible in a timely
fashion. Note that an upgrade is a very cost
effective way to maximize the Physics output of
the pre-existing LHC complex
73
LHC Physics and Upgrade
In general mass reach is increased by 1.5 TeV
(25 ) for Z, heavy SUSY squarks or gluinos or
extra dimension mass scales. A 20 measurement
of the HHH coupling is possible for Higgs masses
from 150 to 200 GeV. However, to realize these
improvements we need to launch the necessary
accelerator RD and maintain the capabilities of
the LHC detectors by upgrading them in a modest
fashion.
74
NSF Tracking
NSF Tracking has been brought up to date. Since
the MRE ends in FY03, this is crucial progress.
This resulted in an EAC increase.
