1 Status of LHCb The pre upgrade years. Running scenario A few selected channels. The LHCb Upgrade The luminosity upgrade The LHC machine and higher luminosities. What is limiting LHCb to profit from larger L? Base-line upgrade scenario. Projected yields of Super LHCb Conclusions - 1 -
2 Muon MWPC RICH2 HPDs OT: straws 5 mm 4 Tm Magnet VELO Si IT DAQ HCAL & ECAL Be beam-pipe Si Trigger Tracker RICH1: mirrors
3 LHCb commissioning in full swing. Expect to be ready for first collisions
4 LHCb pre upgrade years Till summer 2008 Beam-gas, first collisons? Commissioning/shake down detector 2nd half 2008 Expect (hope for) 0.1 fb TeV. Final shake down and Trigger commissioning. First look for NP compatible with low L Stable running at L = cm 2 s 1 Develop full physics program: L 10 fb Upgrade LHCb SuperLHCb Aim for L = cm 2 s 1, L 100 fb
5 CP Violation Charge conjugation: particle anti-particle Parity: reflection in the origin of the space coordinates of a particle. CP violation distinguishes matter from anti-matter: baryogenesis. The CPV in the standard model too small to explain our existence: Leptogenesis? Since ν s have mass, they mix and they will probably have CPV. New physics new source(s) of CPV Studying CPV can reveal new physics, beyond the reach of direct searches. The observation of CPV in the K-system, led Kobayashi and Maskawa to the prediction of the third generation. Hence... But: no smoking gun
6 The Cabibbo-Kobayashi-Maskawa Matrix CKM-matrix describes the charged current interactions of quarks: couplings of W + -boson to up-down quark pairs: V = V ud V us V ub V cd V cs V cb. V td V ts V tb The matrix can be parametrized with four independent parameters, including one phase, which introduces CP violation. Wolfenstein parametrization: λ(= sinθ Cabibbo ), A, ρ and η parameters. 1 λ 2 /2 λ Aλ 3 (ρ i η) V λ 1 λ 2 /2 Aλ 2 + δv, Aλ 3 (1 ρ i η) Aλ 2 1 There are nine unitarity relations in the matrix: triangles. δv contains λ 4 terms - 6 -
7 Compare CPV with CP conserving Non-CPV CKM values from: V ud and V cs from nuclear β-decay and K πlν resp: fixes λ. V ub and V cb : from tree diagram B-decays at LEP/CLEO: fixes A. m d : B-factories. m s : measured by CDF. CPV CKM values from: ɛ K : CPV in K ππ. α, β, γ from B-decays
8 Triangle Status KM nature of CP-violation well established. Next step: LHCb flavour physics program - 8 -
9 LHCb Physics Program Indirect searches for NP in loop induced decays. BR(B s µµ) B mixing parameters. CPV in exclusive b sss hadronic penquin decays. CPV in B decay amplitudes Measurements of exclusive b sll and b sγ Determination of γ using B DK tree decays. Search for LFV in leptonic B-decays NP search in charm sector (mixing, CPV, rare decays) b-hadron spectroscopy, heavy quarkonia etc
10 Expectations based on: Examples of LHCb measurements: full GEANT, spill-over, pile-up, LHCb PYTHIA tuning at 14 TeV (25 % larger multiplicity than CDF 14 TeV), mean-l = cm 2 s 1. Following typical channels: γ measurements, B s µµ, B s J/ψφ, B s φφ, B K µµ
11 Present world average: δ(γ) 25 o Measuring γ
12 Unitary Triangle and γ (a) 2006: Tree only, ///// NP (b) 2006: Loop, NP? (c) 2012: 10 fb 1, γ =? Expect σ(γ) 3 for 10 fb 1. σ(γ) from sides (UTFIT) 6 Lattice improvements could bring this down to σ(γ) sides 1. While increasing statistics, have to resort to theoretically cleanest decays. Upgrade aim: increase statistics with factor
13 BR(B s µµ) Rare loop decay, sensitive to NP. SM: BR=(3.55±0.33)10 9. Example CMSSM (hep-ph/ ), can be strongly enhanced at large tan(β) and interesting gaugino masses. CDF: CL. D0: CL. BR(Bs µµ)
14 BR(B s µµ) Challenge: background rejection: B s mass-resolution: 18 MeV Excellent vertex resolution isolation. Background dominated by double B µx decays. Trigger: p µ T 1 GeV 0.05 fb 1 to overtake Fermilab, 6 fb 1 to have 5σ signal of SM BR
15 B s J/ψ(µµ)φ Extract φ s from golden mode: J/ψ(µµ)φ. φ s strange counterpart of φ d = 2β φ SM s = ± NP (?) in box could increase φ s. 65k J/ψ(µµ)φ/fb 1 σ(φ s ) = with 0.5 fb 1. D0 (1.1 fb 1 ): φ s = 0.79 ± NP amplitude parametrized with h s and σ s LHCb with 10 fb 1 : obtain 3σ evidence of CPV if SM value
16 B s φφ Golden hadronic penguin counterpart: φφ V ts cancels in mixing-decay, hence: CPV-φ 0 NP! 2k φφ/fb 1 (with BR= ) σ(φ NP ) = with 10 fb 1 Compare: 0.4k B 0 φk S /fb 1 σ(sin(2β)) = 0.14 with 10 fb 1 Expect ±0.12 with 2 ab 1 from B-factories
17 B K µµ Loop decay with BR , i.e. sensitive to NP. 3.8k events/fb 1. Estimated B/S=0.4±0.1 σ(a FB (s) = 0) : 0.28 GeV 2 for 10 fb 1. Measure ratio of Wilson coefficients C 7 /C 9 with 7% statistical error
18 B K µµ Other asymmetries: Describe decay as a function of 4 parameters: M 2 µµ, θ l, θ K, φ Transversity amplitude A (2) T : (d) 2 fb 1, 1 σ s=(m µµ ) 2 [GeV 2 ](e) 10 fb 1, 90 % CL Sensitive to MSSM with tan(β)=5 (hep-ph/ ), hence complementary to B s µµ
19 LHC and Luminosity LHC: we (will..) have the machine! L peak LHC 1034 cm 2 s 1, 201n Assume σ visible = : 10 MHz xings with 1 33 : 26 MHz xings with 1 int. nr-int/xings: only factor 2 increase up 33, but spill-over goes linear with L!. SLHC: LHCb does not need it but... L peak SLHC cm 2 s 1, 201n + 4 Baseline scheme 25 ns bunches, but: 50 ns I high I high bunches Interleave with 50 ns I low I low bunches Atlas/CMS xings: I h I h, I l I l, I h I h LHCb xing: I h I l, I l I h, I h I l etc
20 B-rates and Int/xing Assume σ visible = 63 mb. 33 take all xings with 5 33 take all xings with 10 int! Note: σ z (interactions) 50 mm. Typical B-decay length 10 mm
21 Ramping up Peak Luminosity Simulated luminosities (including pile-up, spill-over) up to cm 2 s 1, i.e. 10 design peak luminosity. Trigger: first sub-system which does not scale: Brief overview of the trigger Explanation why it fails Base-line upgrade proposal Tracking Radiation damage
22 Level-0: Largest E T hadron, e(γ) and µ. Bottleneck: 1 MHz max-output rate. L0 limiting yield for larger L peak : High Level Trigger: LHCb Trigger for pedestrians Access to all detector info from day 1. Limitation: CPU (brain?) power. Will improve with Moore s law automatically : plan to replace CPU boxes every 3 years anyway.

23 LHCb Trigger Performance = ) ɛ Trigger : % off-line reconstructed with good B/S: E hadron T 3.5 GeV: ɛ(b hadronic) 25 35% E γ T 2.5 GeV: ɛ(b γx) 30 40% E µ T 1. GeV: ɛ(b µµx) 60 70% Hence: increase lumi AND improve ɛ trigger! Typical trigger storage rates: 200 Hz exclusive B: core program. 600 Hz M µµ > 2.5 GeV: IP-unbiased B J/ψX 300 Hz D : Charm mixing&cpv. For un-triggerable channels: 900 Hz inclusive B (B µx): Data mining. 550 Hz of true B µx B µx trigger: tagging ɛd fully contained, µ-tagged, /2 fb
24 Trigger and Luminosity Trigger: L peak no hadron-trigger gain. hadronic-channels: yield (time ) µ-channels: yield L > : L0-retention > : L0-retention = pp/xing. Result: E T threshold M B
25 Need both p T and Impact Parameter (IP). Upgrade Trigger Proposal Take larger E T seeds, i.e. µ, e-, γ- and hadron-clusters Assume they originate at (0,0,0), and extrapolate to T1-T3. Reco tracks in window around extrapolated candidate: precise p T Connect to VELO tracks: gives IP
26 Trigger Upgrade number of seeds small, hence: Perform whole trigger on CPU farm. Read-out all sub-systems at 40 MHz. Preliminary studies: Event building at 40 MHz, CPU power. Hadron trigger efficiency: L peak, and ɛ hadron 2. Replace all FE-electronics replace VELO/SiT and RICH-HPD, OT-FE, Cal-FE-boards
27 Tracking and Luminosity Tracking & Particle-ID: Note: standard algorithms. VELO tracking not a problem. Straws: L peak spillover is a problem. Address occupancy, especially at large η: R&D... OT straws-occ(no-spillover): 6(4.5) 25(10)% Hence: faster gas, increase Si-IT coverage, scintillating fibres? Tracking environment/algorithms in high(er) occupancy environment. VELO Tracking [%] Tracking efficiency [%] Full spill-over Limited spill-over Ghost rate: full spill-over Ghost rate: limited spill-over Luminosity [ ]
28 Radiation: Integrated L: Radiation designed for L 20 fb 1 radiation damage. Safety factor? Need first running. Affects mainly large η. Address radiation L fb 1. Need to replace VELO (anyway): rad-harder Si, pixels? Inner part of Shashlik Calorimeter: crystals? Inner part of Si-trackers. Remove µ-chamber before Calorimeter
29 Projected Yield vs Time Good B/S [k-events] LHCb L [fb 1 ] B K µµ B s φφ B φk S Year in 21st century KEKB [ab 1 ] LHCb< 2013: L 15fb 1 L = Yield h : constant> Upgrade: Assume ɛ trigger µ unchanged Assume ɛ trigger h 30 60% L = Include tagging efficiency: LHCb ɛd 2 = 0.07 Belle ɛd 2 =
30 Conclusions LHCb is (almost) ready to take over from first generation B-factories. Accumulate 10 fb 1 between st LHCb Collaboration Upgrade Workshop Jan/2007 in Edinburgh: well attended. LHCb Upgrade: draft circulating. EOI... Ramp up upgrade effort to be able to take decision Upgrade specs: Accumulate 100 fb 1 by 2020 Increase ɛ hadron trigger by factor 2.
