Title: Cross sections for production of closed superstrings at high energy colliders in brane world models

Abstract

In brane world string models with large extra dimensions, there are processes where fermion and antifermion (or two gluons) can annihilate producing a light particle (e.g. gluon) carrying transverse momentum and a Kaluza-Klein graviton or an excited closed string that propagates in the extra dimensions. In high energy colliders, this process gives a missing-momentum signature. We compute the total cross section for this process within the context of type II superstring theory in the presence of a D-brane. This includes all missing-energy sources for this string-theory model up to s=8M{sub s}{sup 2}, and it can be used to put new limits on the string scale M{sub s}.

  • The dominant method of energy loss by a loop of cosmic D-strings in models of warped brane inflation is studied. It is shown that the energy loss via Ramond-Ramond field radiation can dominate by many orders of magnitude over the energy radiation via gravitational wave emission. The ratio of these two energy loss mechanisms depends on the energy scale of inflation, the mass scale of string theory, and whether it is a single-throat or a multithroat inflationary scenario. This can have important consequences for the detection of cosmic superstrings in the near future. It is argued that the bounds frommore » cosmic microwave background anisotropies and big bang nucleosynthesis are the dominant cosmological sources to constrain the physical parameters of the network of cosmic superstrings, whereas the role of the gravitational wave-based experiments may be secondary.« less

The small contributions due to charm production are also taken, approximately, intomore » account. We present analytic formulas, admitting a simple intuitive interpretation, which, within theoretical uncertainties, agree with present measurements of the dimuon cross section at the CERN Collider, as well as with the results of Monte Carlo estimates of the ..mu../sup +- /..mu../sup +- //..mu../sup +/..mu../sup -/ ratio (given no B/sup 0/-B-bar /sup 0/ mixing) and the fraction of dimuons arising from cc-bar production.« less
  • We evaluate the cross sections for new heavy fermion production at three Large Hadron Collider energies accurate to next-to-leading order in perturbative quantum chromodynamics. We treat the cases of pair production of heavy quarks via strong interactions, single heavy quark production via electroweak interactions, and the production of heavy leptons. Theoretical uncertainties associated with the choice of the renormalization scale and the parton distribution functions are specified. We derive a simple and useful parametrization of our results which should facilitate phenomenological studies of new physics models that predict new heavy quarks and/or leptons.
