1) Embedding request

The embedding request (Jan's blog)

was approved by spin PWG and Jim made the official request

2) Best guess of BFC options

-------------- Jan , hard pp , no pipelup

For the real data, this is the chain we used for the official production:

3) pre-embedding data vs. M-C comparison
  • Justin compared TPC - looks tragic Nov 10
  • Ilya - BTOW SF for MC - has some eta dependence - Nov 10 fig 4a black curve
4) Optimal GSTAR+BFC settings for W-embedding, simulations

(aimed toward best achievable compatibility with pp500 data)

a) Pythia tune ??

b) M-C W-event processed by GSTAR , output : .fzd
