چکیده

The SuperB asymmetric e+ecollider is designed for 10 36 cm -2 s -1 luminosity and beam energies of 6.7 and 4.18 GeV for e+ and erespectively. The High and Low Energy Rings (HER and LER) have one Interaction Point (IP) with 66 mrad crossing angle. The 1258 m rings fit to the INFN-LNF site at Frascati. The ring emittance is minimized for the high luminosity. The Final Focus (FF) chromaticity correction is optimized for maximum transverse acceptance and energy bandwidth. Included Crab Waist sextupoles suppress betatron resonances induced in the collisions with a large Piwinski angle. The LER Spin Rotator sections provide longitudinally polarized electron beam at the IP. The lattice is flexible for tuning the machine parameters and compatible with reusing the PEP-II magnets, RF cavities and other components. Details of the lattice design are presented.

On the Continuum and Lattice Formulations of N = 4 D = 3 Twisted Super Yang - Mills

Employing a twisted superspace with eight supercharges, we describe an off-shell formulation of N = 4 D = 3 twisted super Yang-Mills in the continuum spacetime which underlies the recent proposal of N = 4 D = 3 twisted super Yang-Mills on a lattice [6]. By a dimensional reduction from the N = 2 D = 4, we explore the two possible topological twists of N = 4 D = 3 and then show that the lattice f...

Progress in four-dimensional lattice supersymmetry

We are entering an era where a number of large-scale lattice simulations of four-dimensional supersymmetric theories are under way. Moreover, proposals for how to approach such studies continue to progress. One particular line of research in this direction is described here. General actions for super-QCD, including counterterms required on the lattice, are given. We obtain the number of fine-tu...

Lattice Super-Yang-Mills Using Domain Wall Fermions in the Chiral Limit

Lattice N = 1 super-Yang-Mills theory formulated using Ginsparg-Wilson fermions provides a rigorous non-perturbative definition of the continuum theory that requires no fine-tuning as the lattice spacing is reduced to zero. Domain wall fermions are one explicit scheme for achieving this and using them we have performed large scale Monte Carlo simulations of the theory for gauge group SU(2). We ...

Super Yang-Mills on the lattice with domain wall fermions

The dynamical N = 1, SU(2) Super Yang-Mills theory is studied on the lattice using a new lattice fermion regulator, domain wall fermions. This formulation even at non-zero lattice spacing does not require fine-tuning, has improved chiral properties and can produce topological zero-mode phenomena. Numerical simulations of the full theory on lattices with the topology of a torus indicate the form...

Phonon modes of MgB2: super-lattice structures and spectral response.

Micrometre-sized MgB2 crystals of varying quality, synthesized at low temperature and autogenous pressure, are compared using a combination of Raman and infra-red (IR) spectroscopy. These data, which include new peak positions in both spectroscopies for high quality MgB2, are interpreted using DFT calculations on phonon behaviour for symmetry-related structures. Raman and IR activity additional...

Super lattice formation of an array of volatile wetting droplets

For an ordered array of critical volatile wetting droplets the formation of a super lattice by an Ostwald-ripening like competition process is considered. The underlying diffusion problem is treated within a quasistatic approximation and to first order in the inverse droplets distance. The approach is rather general but a square lattice and a triangular lattice are studied explicitly. Dispersio...
