Consiglio di Sezione INFN
Milano Bicocca - 10 luglio 2018
M. Calvi
LHCb detector & data taking
• Third year of Run2 data-taking, LHC e LHCb in very good shape.
• Aim at 2.5 fb-1 this year for a total >9 fb-1 Run1+Run2
• Fill at best the bandwidth with NoBias
trigger (for Charm Physics) during
intensity ramp-up
• Run-time alignment and calibration of the
detector
LHCb Collaboration
• Collaboration growing progressively every year
Now 79 Institutes from 19 Countries
LHCb Physics: LHCb papers
• Large variety of Physics topics: not only beauty & charm,
electroweak, heavy-ion, fixed target etc..
• 431 papers in total,
• 19 with the Editorial board
• about 35 under review
LHCb Physics: Attività analisi in Bicocca
• Misura di sin(2beff) da B0 à D*+D-
N.Belloli, M.Calvi, et al.
Misura di CPV da fit della distribuzione del decay-time di eventi flavour-
tagged. Sensitività prevista migliore BaBar+Belle.
Analisi su dati RUN1 +RUN2 in corso.
B0àD*D
D0àK3p
• Violazione di CP nei decadimenti B0(s) àhh (h=p,K) D. Fazzini, et al. Misura parametri di violazione di CP da fit della distribuzione del decay-time di eventi flavour-tagged. Fit simultaneo a Kp, pp, KK. • Analisi su dati RUN 1 completa ( Sumbitted to PRD) >4s CPV in Bs • Analisi Run2 in corso
• Test di universalità leptonica nei decadimenti semileptonici bàcln: R(D(*)) M.Calvi, S.Meloni, et al. Universalità degli accoppiamenti ew alle diverse famiglie di leptoni, accidentale nel MS, messa in dubbio dalle misure alla Y(4S) e LHCb. R(D+) = B(B0àD+tn) / B(B0àD+µn) Misura simultanea di R(D+) e R(D*) con D*0àD-p0 Usa tàµnn. • Analisi su dati RUN 2 in corso.
• Misura di |Vub|/|Vcb| da Bs àKµn
M.Calvi, et al.
Vub è il parametro della matrice CKM meno noto fino ad ora.
Si misura il branching fraction di Bs àKµn rispetto Bs à Dsµn
RFF = ratio of form factors
calculated using LQCD
Analisi iniziata a Milano, in collaborazione con Edimburgo e Heidelberg.
In finalizzazione.
LHCb Upgrade
• Comprehensive Upgrade to be
ready for Run 3, main focus of the
Collaboration
• Instantaneous luminosity to be
increased by a factor five
• Full-detector read-out at 40 MHz
• Production and installation
almost all on-track
• Ongoing effort to have full software trigger at 40MHz.
• “Upgrade Software and Computing” TDR released
• Working on computing model (document for 2018 Q3)

UPGRADE II
Expression of tInterest
• EoI sumbitted in February 2017
Expression Of Interest by the LHCb Collaboration to the
LHCC, for an experimental programme going beyond the
CERN/LHCC 2017-0nn
Opportunities in flavour physics,
and beyond, in the HL-LHC era
current LHCb Phase-I Upgrade plan, aiming at a fuller
Expression of Interest exploitation of the Flavor physics potential of the HL-LHC.
• Feasibility studied by LHC Accelerator Division
CERN-ACC-NOTE-2018-0038: “A range of potential solutions for operating
LHCb Upgrade II as a luminosity of up to 2 x 1034cm-2s-1 and permitting the
collection of 300 fb-1 or more at IP8 during the envisaged lifetime of the LHC.”
• Physics case:
LHCb document ready (under review), to be presented to LHCC in September.
Several talks at the “2nd Workshop on the Physics of HL-LHC and perspective of
HE-LHC” 18-20 June 2018
Timeline
• Upgrade II:
Install in LS4 after Upgrade I, aim to integrate ~300 fb-1 within a couple of LHC runs.
Some detector improvements could be already installed in LS3, taking advantage of very
long shutdown (Upgrade Ib)
• Run3 à ~ 25 fb-1
• Run4à ~ 50 fb-1
• Run5 à ~ 300 fb-1 ?2017-18 LHCb talks Milano Bicocca International Conferences Marta Calvi “B anomalies at LHCb” Flavour changing and conserving processes, FCCP2017” Capri, Italia 7-9-2017 Lucia Grillo “B results on CPV, CKM measurements , rare decays” Physics in Collision Prague, Czech Republic, 2017-09-04 Marta Calvi “Lepton-flavour universality tests at LHCb” Rencontres de Physique de la Vallée d'Aoste, La Thuile, Italy 2018-02-25 Marta Calvi “Vub measurements at LHCb” Challenges in Semileptonic Decays, Mainz, Germany, 9-13 Apr 2018 Davide Fazzini “Flavour Tagging in the LHCb experiment” Large Hadron Collider Physics Conference (LHCP2018) Bologna, Italia, 4-9 June 2018
