R-axion detection at LHC

Hock-Seng Goh, Masahiro Ibe

Supersymmetric models with spontaneously broken approximate R-symmetry contain a light spin 0 particle, the R-axion. The properties of the particle can be a powerful probe of the s…

Charmonium production in e+e- to ψ+ X(c\bar c) and e+e- to D*D_J

Frank Close, Clark Downum

The dominance of chi_0 in the data for e+e- to psi + chi_J(c\bar{c}) is shown to violate OZI factorization. Single gluon exchange gives a non-factorizing effective S.L interaction…

Threshold resummation for squark-antisquark and gluino-pair production at the LHC

A. Kulesza, L. Motyka

We study the effect of soft gluon emission in the hadroproduction of squark-antisquark and gluino-gluino pairs at the next-to-leading logarithmic (NLL) accuracy within the framewor…

On the Numerical Evaluation of One-Loop Amplitudes: the Gluonic Case

W. T. Giele, G. Zanderighi

We develop an algorithm of polynomial complexity for evaluating one-loop amplitudes with an arbitrary number of external particles. The algorithm is implemented in the Rocket progr…

Non-thermal Dark Matter and the Moduli Problem in String Frameworks

Bobby S. Acharya, Piyush Kumar, Konstantin Bobkov +3

We address the cosmological moduli/gravitino problems and the issue of too little thermal but excessive non-thermal dark matter from the decays of moduli. The main examples we stud…

Inducing the mu and the B mu Term by the Radion and the 5d Chern-Simons Term

Arthur Hebecker, John March-Russell, Robert Ziegler

In 5-dimensional models with gauge-Higgs unification, the F-term vacuum expectation value of the radion provides, in close analogy to the Giudice-Masiero mechanism, a natural sourc…
