Linac*LHC Based ep, Gamma-p, eA, Gamma-A and FEL Gamma-A Colliders: Luminosity and Physics

Main parameters and physics goals of different colliders, which can be realized if a special 1 TeV energy linear electron accelerator or corresponding linear collider is constructed tangential to LHC, are discussed. It is shown that L_(ep)=10^(32)cm^(-2)s^(-1) at sqrt(s_(ep))=5.29 TeV can be achieved within moderate upgrade of LHC parameters. Then, Gamma-p collider with he same luminosity and sqrt(s)=4.82 TeV can be realized using Compton backscattering of laser beam off the electron beam. Concerning the nucleus beam, L*A=10^(31)cm^(-2)s^(-1) can be achieved at least for light and medium nuclei for both eA and Gamma-A options. Finally, colliding of FEL beam from an electron linac and nucleus beam from LHC will give a new opportunity to investigate nuclear spektroscopy and photo-nuclei reactions.

TAC Proposal for Fundamental and Applied Research: Linac-Ring Type Phi-Factory

Main parameters of linac-ring type $phi$-factory proposed as the part of the Turkic Accelerator Complex (TAC) in the framework of ATAM Science Sity Project are discussed. Two sets of parameters, corresponding to E=130(260) MeV for electron linac and E=2000(1000) MeV positron ring, are considered. It is swoun that, in principle, L=10^(34)cm^(-2)s^(-1) can be achieved, which is more than an order exceeds the design luminosity of the DA$Phi$NE. Parameters of the FEL based on electron linac and synchrotron radiation sources based on the positron ring are estimated.

Why the Four SM Families

The flavor democracy favors the existence of the nearly degenerate fourth SM family, whereas the fifth SM family is disfavored both by the mass phenomenology and precision tests of the Standard Model. The multi-hundreds GeV fourth family quarks will be copiously produced at the LHC. However, the first indication of the fourth family may come from the Higgs search at the upgraded Tevatron.

Linac*LHC based ep, gamma-p, eA, gamma-A and FEL gamma-A Colliders

Main parameters of different colliders which can be realized if a special 1 TeV energy linear electron accelerator or corresponding linear collider is constructed tangential to LHC are estimated. It is shown that L_ep=10^32cm^-2s^-1 at sqrt(s_ep)=5.29 TeV can be achieved within moderate upgrade of LHC parameters. Then, gamma-p collider with the same luminosity and sqrt(s)=4.82 TeV can be realized using Compton backscattering of laser beam off the electron beam. Concerning the nucleus beam, L*A=10^31cm^-2s^-1 can be achieved at least for light and medium nuclei both for eA and gamma-A options. Finally, colliding of the FEL beam from an electron linac with nucleus beams from LHC will give a new opportunity to investigate nuclear spectroscopy and photo-nuclei reactions.

Three Remarks on the MSSM

First of all, "right" sneutrino can be the lightest supersymmetric particle. Then, the flavor democracy favors large value of the tan^($beta$). Finally, the huge number of free parameters in the three families MSSM may be considered as an indication of SUSY at preonic level.

Probing a Nucleon Spin Structure at TESLA by the Real Polarized Gamma Beam

The recent proposals concerning the usage of the real polarized gamma beam, obtained by the Compton backscattering of the laser photons off the electron beams from either the linear or circular accelerators were considered. The heavy quark photoproduction process giving a unique opportunity to measure polarized gluon distribution was investigated.

New Tool for "Old" Nuclear Physics: FEL gamma-Nucleus Colliders

A new method has been considered to investigate the scattering reactions with photons on fully ionized nuclei. To induce $γ$-nucleus collisions a free electron laser and a heavy ion synchrotron have been considered bringing them together. Main parameters of the collider (especially LHC and HERA for the acceleration of nuclei) have been estimated. Rough calculations have also been made for the cross sections of the excited nuclei production. Finally, some design problems involving the collider have been considered.

Linac-Ring Type Colliders: Fourth Way To TeV Scale

The present status of suggested linac-ring type ep and gamma-p colliders is reviewed. The main parameters of these machines as well as e-nucleus and gamma-nucleus colliders are considered. It is shown that sufficiently high luminosities may be achieved with a reasonable improvement of proton and electron beam parameters.
