The Budker Institute of Nuclear Physics is one of the major centres of advanced study of nuclear physics in Russia. It is located in the Siberian town Akademgorodok, on Academician Lavrentiev Avenue. The institute was founded by Gersh Itskovich Budker in 1959. Following his death in 1977, the institute was renamed in honour of Academician Budker.Despite its name, the centre was not involved either with military atomic science or nuclear reactors— instead, its concentration was on high-energy physics and particle physics. In 1961 the institute began building VEP-1, the first particle accelerator in the world which collided two beams of particles. The BINP now employs over 3000 people, and hosts several research groups and facilities. Wikipedia.

Proton beam driven plasma wakefield acceleration was recently proposed as a way to bring electrons to TeV energy range in a single plasma section. Here we present a detailed numerical analysis of this acceleration scheme. We identify the main effects limiting acceleration efficiency and ultimate energy gain, and formulate optimum conditions for acceleration. © 2010 The American Physical Society.

We show that dimensional recurrence relation and analytical properties of the loop integrals as functions of complex variable D (space-time dimensionality) provide a regular way to derive analytical representations of loop integrals. The representations derived have a form of exponentially converging sums. Several examples of the developed technique are given. © 2009 Elsevier B.V. All rights reserved.

The four-fermion gravitational interaction is induced by torsion, and gets essential on the Planck scale. On this scale, the axial-axial contribution dominates strongly the discussed interaction. The energy-momentum tensor, generated by this contribution, is analyzed, as well as stability of the problem with respect to compression. The trace of this energy-momentum tensor can be negative. © 2012 Elsevier B.V.

A novel method of studying e+e- annihilation into hadrons using initial state radiation at e+e- colliders is described. After a brief history of the method, its theoretical foundations are considered. Numerous experiments in which exclusive cross sections of e +e- annihilation into hadrons below the center-of-mass energy of 5 GeV have been measured are presented. Some applications of the experimental results to fundamental tests of the standard model are listed. © 2011 American Physical Society.

A high energy particle beam propagating in a uniform plasma is subject to the transverse two-stream instability that first transforms the beam into the train of microbunches and then quickly destroys that train by transverse wakefields. By the proper longitudinal inhomogeneity of the plasma density, it is possible to stop the instability action at the stage of microbunches and form the bunch train that can resonantly excite plasma wakefields over a long distance. The latter feature is vital for proton beam driven plasma wakefield acceleration that was recently proposed as a way to bring electrons to TeV energy range in a single plasma section. © 2011 American Institute of Physics.
