2. Achievements from the LHC machine

Mike Lamont (CERN)

11/08/2014, 10:30

This talk will focus on the challenges encountered in run 1, the prospects for run 2, and longer-term perspectives up to 2035

3. Measurement of the luminosity at LHC

Gabriel Anders (CERN)

11/08/2014, 11:00

In this talk, the techniques used in the ATLAS, CMS and LHCb experiments to measure the luminosity will be exposed. The similarities and differences will be outlined, and an emphasis will be put on describing the related systematic uncertainties.

11. Review of theoretical progresses from before to after run 1 and prospects

Gian Piero Passarino (Universita e INFN (IT))

11/08/2014, 11:20

5. Run 1 legacy performance: LHCb

Giacomo Graziani (Universita e INFN (IT))

11/08/2014, 11:50

In this talk, the performance of the LHCb experiment during the LHC run 1 will be exposed. A special emphasis will be put on what worked better or worse than planned, and the lessons learnt for run 2.

7. Challenges of particle reconstruction in hadronic environnement

Lindsey Gray (Fermi National Accelerator Lab. (US))

11/08/2014, 12:10

In this talk, the challenges of particle reconstruction in an hadronic environnement will be exposed. A special emphasis will be put on particle flow techniques, and a the most striking improvements will be described. (note: the speaker should coordinate this talk with the “Run 1 legacy performance” talks from ATLAS and CMS).

8. Run 1 legacy performance: Tracking, flavour tagging, muons

Andrea Rizzi (Sezione di Pisa (IT)), Edward Moyse (University of Massachusetts (US))

11/08/2014, 15:45

In this talk, the run 1 legacy performance of the tracking, heavy-flavor tagging and muon reconstruction in the ATLAS and CMS experiments will be described, as well as the associated systematic uncertainties. The two speakers should try to enlight the differences of performances between the two experiments, and explain what worked better/worse than planned, as well as the lessons for the run 2.

10. Run 1 legacy performance: Jets/ETMiss/tau

Dr Tai Sakuma (University of Bristol (GB)), Toshi Sumida (Kyoto University (JP))

11/08/2014, 16:10

In this talk, the run 1 legacy performance of jet, missing transverse energy and tau reconstruction in the ATLAS and CMS experiments will be described, as well as the associated systematic uncertainties. The two speakers should try to enlight the differences of performances between the two experiments, and explain what worked better/worse than planned, as well as the lessons for the run 2.

9. Run 1 legacy performance: electrons/photons

Daniele Benedetti (Purdue University (US)), Denis Oliveira Damazio (Brookhaven National Laboratory (US))

11/08/2014, 16:35

In this talk, the run 1 legacy performance of the electron and photon reconstruction and identification in the ATLAS and CMS experiments will be described, as well as the associated systematic uncertainties. The two speakers should try to enlight the differences of performances between the two experiments, and explain what worked better/worse than planned, as well as the lessons for the run 2.

12. Discussion Session

Luca Malgeri (CERN)

11/08/2014, 17:00

“Surprises and disappointments during run 1” (mostly performance-wise). Some suggestions to be discussed: (i) What are the reasons for the "early" Scalar boson discovery wrt earlier expectations? (ii) Operation modes (reprocessing, calibration, …). (iii) MC usage (new features w.r.t. stability). (iv) data/MC agreement. etc.
