ON THE APPLICATION OF ®Z 0 +j etEVENTS FOR DETERMINING THE GLUON DISTRIBUTION IN AP ROTON AT THE LHC

It is shown that the samples of ®Z 0 +jetevents, collected at the LHC with the integrated luminosity Lint =2 0fb −1 , may have enough statistics for determining the gluon distribution inside a proton in the region of 2 · 10 −4 x 1.0 at Q 2 values in the interval of 0.9 · 10 3 Q 2 4 · 10 4 (GeV/c) 2 .A possibility of the background events suppression by the use of the ®Z 0 +j etevents selection criteria is also demonstrated. �µ± § ´µ, IEµ ¸µiOE¨O ® Z 0 + ¸E·EO¯, ´ i· ´´O¥ ´ LHC ¸ ¨´E¥£· ²O´µ° ¸¢¥E¨³µ¸EOO Lint = 20 Ei −1 , ³µ£EE µi² ¤ EO ¤µ¸E EµI´µ° ¸E E¨¸E¨±µ° ¤²O µ¶·¥¤¥²¥´¨O £²Oµ´´µ£µ · ¸¶·¥¤¥²¥´¨O ¢ ¶·µEµ´¥ ¢ µi² ¸E¨ 2·10 −4 x 1,0 ¶·¨ §´ I¥´¨OI Q 2 ¢ ¨´E¥·¢ ²¥ 0,9·10 3 Q 2 4·10 4 (ƒO‚/c) 2 .
