On integrating out shortdistance physics
"... Abstract. I consider a special atomic scattering problem to demonstrate that in a reasonably formulated theory the integration out of shortdistance physics occurs automatically. I propose to build QFT in a similar way. 1. ..."

1 Short distance physics with heavy quark potentials ∗
, 2001
"... We present lattice studies of heavy quark potentials in the quenched approximation of QCD at finite temperatures. Both, the color singlet and color averaged potentials are calculated. While the potentials are well known at large distances, we give a detailed analysis of their short distance behavior ..."

Signatures of short distance physics in the cosmic microwave background,” Phys
 Rev. D
"... We systematically investigate the effect of short distance physics on the spectrum of temperature anistropies in the Cosmic Microwave Background produced during inflation. We present a general argument–assuming only low energy locality–that the size of such effects are of order H 2 /M 2, where H is ..."

ITEPTH74/99 Confinement and short distance physics
, 2000
"... We consider nonperturbative effects at short distances in theories with confinement. The analysis is straightforward within the Abelian models in which the confinement arises on classical level. In all cases considered (compact U(1) in 3D and 4D, dual Abelian Higgs model) there are non–perturbative ..."

Short Distance Physics and Initial State Effects on the CMB Power Spectrum
, 809
"... We investigate a modification in the action of inflaton due to noncommutativity leads to a nonstandard initial vacuum and oscillatory corrections in the initial power spectrum. We show that the presence of these oscillations causes a drop in the WMAP χ 2 about ∆χ 2 ∼ 8.5. As a bonus, from the parame ..."

We investigate a modification in the action of inflaton due to noncommutativity leads to a nonstandard initial vacuum and oscillatory corrections in the initial power spectrum. We show that the presence of these oscillations causes a drop in the WMAP χ 2 about ∆χ 2 ∼ 8.5. As a bonus, from the parameter estimation done in this work, we show that the noncommutative parameters can be precisely bound to 10 16 GeV or 10 4 GeV depending on the inflation scale. 1
hepph/0106219 High Energy Colliders as Black Hole Factories: The End of Short Distance Physics
, 2001
"... If the fundamental Planck scale is of order a TeV, as the case in some extradimensions scenarios, future hadron colliders such as the Large Hadron Collider will be black hole factories. The nonperturbative process of black hole formation and decay by Hawking evaporation gives rise to spectacular ev ..."

the Planck scale are cloaked behind a horizon, thus limiting the ability to probe short distances. The high energy black hole cross section grows with energy at a rate determined by the dimensionality and geometry of the extra dimensions. This dependence therefore probes the extra dimensions at distances
Extracting shortdistance physics from KL,S → π 0 e + e − decays
, 2003
"... We present a new analysis of the rare decay KL → π0e + e − taking into account important experimental progress that has recently been achieved in measuring KL → π0γγ and KS → π0e + e −. This includes a brief review of the direct CPviolating component, a calculation of the indirect CPviolating cont ..."

We present a new analysis of the rare decay KL → π0e + e − taking into account important experimental progress that has recently been achieved in measuring KL → π0γγ and KS → π0e + e −. This includes a brief review of the direct CPviolating component, a calculation of the indirect CPviolating contribution, which is now possible after the measurement of KS → π0e + e − , and a reanalysis of the CP conserving part. The latter is shown to be negligible, based on experimental input from KL → π0γγ, a more general treatment of the form factor entering the dispersive contribution, and on a comparison with the CP violating rate, which can now be estimated reliably. We predict B(KL → π0e + e − ) = (3.2 +1.2 −0.8) × 10−11 in the Standard Model, dominated by CP violation with a sizable contribution ( ∼ 40%) from the direct effect, largely through interference The flavourchanging neutralcurrent transition KL → π 0 e + e − has been recognized since a long time to be one of the most interesting rare kaon decays. It shows an intriguing
Fast Parallel Algorithms for ShortRange Molecular Dynamics
 JOURNAL OF COMPUTATIONAL PHYSICS
, 1995
"... Three parallel algorithms for classical molecular dynamics are presented. The first assigns each processor a fixed subset of atoms; the second assigns each a fixed subset of interatomic forces to compute; the third assigns each a fixed spatial region. The algorithms are suitable for molecular dyn ..."
