1 Giorgio and CDF Celebrating 70 years of Giorgio and >25 years of CDF Henry Frisch Univ. of Chicago

2 A Personal Note: I first met Giorgio at the 1974 London Conf- we had just found ‘direct muons’ (charm): He came to the session in tennis whites + rackets, with charm and enthusiasm. “The lack of Pt ‘bumps’ means that there are no significant heavy objects (M from 3 to 10 GeV) that decay into 2 leptons”-Leon

3 Intro: Giorgio’s Physics Interests: See Fermi’s Yale Lectures of 1951 “Electromagnetic and Yukawa Interaction Constants:” “Perhaps future developments..will enable us to understand the reasons for the existence and the strength of the various interactions.”- Fermi

4 The Start of CDF Jan 1997- Cronin heads Colliding Beam Dept.- - 2 Init. Designs: one magnetic, one not Wilson decrees 10M$ cap on detector cost (!) Oct. 78- Wilson resigns- Lederman new Dir. Oct. 79- CDF Dept formed; Alvin Head of CDF Giorgio had already approached Alvin – Pisa is one of the founding institutions at formal start. Fig. from TDR 1981 N.B.

5 CDF Technical Design Report Author List 1981 G. Bellettini, M.Bertani, L. Bosisio, C.Bradaschia, R.DelFabbro,E.Focardi, M.A. Giorgi, A.Menzione, L.Ristori, A.Scribano, G.Tonelli S. Bertolucci,M.Cordelli, P. Giormini, P.Sermoneta

6 HJF and HJ, eds. Big Step- Technical Design Report

7 Draft of Fig. 1 of TDR Remarkable in that it’s what we built!

8 1981 Vision of top, b-physics! From Silicon Section of TDR- Aldo, Giorgio,… Remarkable Paragraph (amazingly forsighted).

9 The SVX- key to the top discovery and all CDF b-physics Critical Dev! Aldo,Giorgio, et al. 1981 TDR AS BUILT-92

10 Central Hadron Calorimeters 1981 TDRAS BUILT

11 The detector comes to life…82-85

12 Some of the crew at work: B0

13 More B0

14 Giorgio’s Physics on CDF: Long Interest in High-Pt pheno-mena (<1974) Top Discovery (94/5) Top Properties Strong Drive for New Effects- 1975 Yerevan Lectures

15 The Top “Evidence” and Discovery Giorgio at the announcement March 2, 1995; Giorgio Co-spokesperson

16 1987 Integrated Luminosity (nb) Run 2 Lum (pb) Evolution of the Tevatron Collider

17 CDF in the Present Collisions at s-hat>1TeV 2 CDF Run2 Inclusive Jet Spectrum

18 (Evelyn Thompson’s ICHEP talk) Run 2 Top Measurements--

19 M top = 179.6 (stat) ± 6.8 (sys) GeV/c 2 +6.4 -6.3 Run 2 Top Mass- l+jets

21 Giorgio’s Other LongLasting Contributions: Broad Italian Component Many Generations of Excellent Young Students (preLHC-school) Support for non-US physicists (Russians,others,…) CDF presence at Conferences- La Thuile, PbarP, Elba,... General Level of Culture- (next slide)

22 Tita demonstrates typical Fermilab cuisine pre-Giorgio

23 Thank you Giorgio- from all of CDF The End
