1 Future Prospects BTeV at Fermilab: -Physics Expectations Will Johns Vanderbilt University HCP2004, MSU East Lansing MI June 16, 2004
2 Interference in D + K* µν Abject lesson in high statistics Suppose there is an indication of a new coupling in a well understood decay Case in point (means the one I know ) D + K * 0 µ + ν Focus K* signal Yield 31,254 Data MC F-B asymmetry mkπ ( ) K* µν interferes with S- wave Kπ and creates a forwardbackward asymmetry in the K* decay angle with a mass variation due to the varying BW phase -15% F-B asymmetry! matches model The S-wave amplitude is about 7% of the K* BW with a 45 o relative phase
3 Small effects are tough to see Shouldn t a 7% effect been seen before? E791(digitized) This is roughly a 1.5 sigma effect (Tough to see!!) FOCUS (~E791 cuts) ~10xStats ~6 sigma effect
4 So What? New Physics, Standard Model subtleties etc. can be locked in DISTRIBUTIONS rather than PEAKS -Look for new Physics!- (Away from poles!) MSSM R-Parity Violating Terms Boost Rates (Burdman, Golowich, Hewett, Pakvasa) [hep-ph/ v2]
5 Actually, it s even more important in this case R-Parity Violating Enhancement is Clear yet SM Predictions Differ (integrated rates differ x2) MSSM SM Use Large Samples to measure SM effects too. (Burdman, Golowich, Hewett, Pakvasa) [hep-ph/ v2] S. Fajfer, S. Prelovsek and P. Singer Phys. Rev. D Volume 64, (2001)
6 Why the Mom and Apple Pie story? Our lessons with high statistics are important Coupling effects can be SUBTLE A factor of even 10 can be important More than one experiment needs to look at the data FOCUS Ds(2317) BaBar Need even more statistics to bring out physics BaBar B X S hep-ex lepton-lepton Mass spectra
7 Where will giga-heavy hadron statistics come from? pp bb+x b production peaks at large angles with large bb correlation The higher momentum b s are at larger η s βγ b production angle b production angle η = -ln(tan θ ) 2
8 How do we measure 10 s x giga-statistics? An Internet that never slows down due to traffic, hardware failures, different tasks etc. (within limits of course) DAQ Idea: find primary vertices & detached tracks from b or c TRIGGER decays Inner pixel region Pixel hits from 3 stations are sent to an FPGA tracker that matches interior and exterior track hits Interior and exterior triplets are sent to a farm of DSPs to complete the pattern recognition: interior/exterior triplet matcher fake-track removal x y x y x y
9 Pixels really cut down on confusion-- --really Full GEANT has multiple scattering, bremsstrahlung, pair conversions, hadronic interactions and decays in flight; smears hits and refits the tracks using Kalman Filter. No pattern recognition (except for trigger). However, we do not expect large pattern recognition problems This track density is 3x higher than what is expected in BTeV! Target From our test beam run Detailed studies of efficiency and rejection for up to an average of six interactions/crossing 3.2 mm X 4.8mm 7.2 mm X 8.0 mm
10 How do you take full advantage of a loose trigger? For a requirement of at least 2 tracks detached by more than 4σ from a primary (interaction) vertex State efficiency(%) state efficiency(%) B π + π - 55 B o K + π - 54 B s D s K 70 B o J/ψ K s 50 B - D o K - 60 B s J/ψK * 69 B - K s π - 40 B o K * γ 40 -Need good pion/kaon separation (RICH) -Need good EM calorimetry -Need good muon ID -Need tracking over a large volume of 2 int/crossing
11 Why would you want a loose trigger? Precision Standard Model tests require many different modes α Over-constraining the CKM matrix with precision will be challenging η γ β 0 d 0 s B mixing B mixing 0 CPV in K mixing Cabibbo suppressed B ρ semileptonic decay
12 Why would you want to take advantage? Detector requirements in order to map out the CKM triangles.

21 Conclusions Multiple year running to see subtle effects in rare decays even with BTeV AND LHCb BTeV Open Trigger and Detector Choices are suited to a variety of analysis We can argue about startup scenarios but: - In the steady state LHCb gets ~0.8 fb -1 - In the steady state BTeV gets ~1.6 fb -1 BTeV has an advantage in the steady state (more - Awaiting CD-1 official approval (reviews done) - Base-lining this summer CD-2, CD-3x Winter
22 Backup slide 1 LHC running time In steady state mode, after a few years, they are scheduled to run 160 days a year for physics MINUS running for Heavy Ions - estimate 139 days on pp (see Collier, BTeV-Doc (We can discuss offline)) LHCb will start running at 2.8x1032; this gives using formula in Collier 0.8 fb-1 per calendar year First year will see limited running at 75 ns bunch spacing; LHCb needs special setup, will also serve to limit luminosity Second year will switch from 75 ns to 25 ns when possible LHC schedule (LHCb-1) Nominal: start April 1, 2007 (we know already that this is now August, but we have not factored that in) We predict LHCb 2007 integrated luminosity to be 0.1 fb-1 Since the first quarter of 2008 is still in the first year of tuning we give them 0.6 fb-1 They get the full 0.8 fb-1 in 2009
23 Backup slide 2 BTeV s Schedule Stage I starts August 1, 2009 Then we run until July 1, 2010 Expect about 1 month to commission IR Then its up to us to produce physics Summary of Stage 1 Estimate 6 months running time Lab says that we will run 10 months a year and get 1.6 fb-1 Thus this is a 1 fb-1 run We have 75% of our normal rate on all charged flavor tagged modes We have 75% x 60% = 45% of our normal rate on flavor tagged modes with neutrals
