[Saratov period of life of Alexander Nikolayevich Bakulev (to his 130th birthday)].

This article deals with the bibliographic information relating to the Saratov period of life of Alexander Nikolayevich Bakulev, his scientific and practical activity at the Department of Hospital Surgery of the Saratov Medical University under the leadership of the Department's founder, Sergey Ivanovich Spasokukotsky having exerted the key influence on the formation of A.N. Bakulev as a surgeon and scientist.

Determination of the strange-quark density of the proton from ATLAS measurements of the W→ℓν and Z→ℓℓ cross sections.

A QCD analysis is reported of ATLAS data on inclusive W(±) and Z boson production in pp collisions at the LHC, jointly with ep deep-inelastic scattering data from HERA. The ATLAS data exhibit sensitivity to the light quark sea composition and magnitude at Bjorken x∼0.01.

Search for pair production of a heavy up-type quark decaying to a W boson and a b quark in the lepton + jets channel with the ATLAS detector.

A search is presented for production of a heavy up-type quark (t') together with its antiparticle, assuming subsequent decay to a W boson and a b quark, t't[over ¯]'→W(+)bW(-)b[over ¯]. The search is based on 1.04 fb(-1) of proton-proton collisions at √[s]=7 TeV collected by the ATLAS detector at the CERN Large Hadron Collider.
