Quarkonia g-production in UPC A+A @ LHC (I)

• Some key figures:

• Max. sgA(LHC) ≈ 900 GeV > 3 – 5×sgp(HERA)

• Max. sgg (LHC) ≈ 160 GeV ≈ sgg (LEP)

• LHC (y=0): x(J/) ~4·10-4 , x(¡)~10-3

• LHC (y=3): x(J/) ~ 2·10-5 , x(¡)~10-4

• g+A J/+A

• in UPC A+A versus √sNN:

• LHC QQbar cross-sections:

• (first time ¡ measurable in UPC)
