FB Asymmetry at Tevatron

Kihyeon Cho 8

We used dimension-6 four quark operators with all the possible Dirac and color structures.

We considered the s-, t- and u- channel exchanges of spin-0 and spin-1 particles whose color quantum number is either singlet, octet, triplet or sextet.

Our results encode the necessary conditions for the underlying new physics in a compact and an effective way when those new particles are too heavy to be produced at the Tevatron.

Ongoing analysis @KISTI with Paris group• Analyzed 5.2 fb-1

• Including new trigger (TTT) => adds 25% more data • New analysis => cross-check• Optimized data selection => getting more data than just from

multiplying with the increase in luminosity.• Untagged analysis in progress with TTT and comparing with

Dimuons

MC Production StatusR. Tesarek’s procedure for MC production of TTT events works smoothly and rather well

LPNHE is at the NTUPLING phase. Collaboration with KISTI will certainly accelerate the process

July 6th, 2010 33

LPNHE & KISTIOnce the SAM Station is installed, KISTI & LPNHE can use the KISTI Grid for the production of data as well as MC files. => Waiting for SAM Station at GSDC

A double copy of the .root files can be stored in both places.

Summary

New CDF members of KISTI are welcome.

HEP team at KISTI contributes to CDF by paradigm of e-Science for top physics and Bs physics.

We work on remote control room and FKPPL very well.

Kihyeon Cho

Thank you.
