Improvements in X-band transmitter phase stability through klystron body temperature regulation
This article describes the techniques used and experimental results obtained in improving transmitter stability by control of the klystron body temperature. Related work in the measurement of klystron phase control parameters (pushing factors) is also discussed. The contribution of waveguide temperature excursions to uplink phase stability is presented. Suggestions are made as to the direction of future work in this area
Vector triplets at the LHC
Several popular extensions of the Standard Model predict extra vector fields
that transform as triplets under the gauge group SU(2)_L. These multiplets
contain Z' and W' bosons, with masses and couplings related by gauge
invariance. We review some model-independent results about these new vector
bosons, with emphasis on di-lepton and lepton-plus-missing-energy signals at
the LHC.Comment: LaTex 5 pages. Talk by M. Perez-Victoria at LHCP 2013, Barcelona,

Solving the Nose-Hoover thermostat for Nuclear Pasta
In this work we present a calculation of the hamiltonian variables solving
the molecular dynamics equations of motion for a system of nuclear matter
relevant to the description of nuclear pasta. The temperature is kept fixed by
using the Nos\'{e}-Hoover Thermostat and the interaction is modelled via a
semiclassical potential depending on both positions and momenta.Comment: 7 pages, 3 figures. Journal of Mathematical Chemistry, in pres
