Linear Time-Dependent Invariants for Scalar Fields and Noether's Theorem
The infinite number of time-dependent linear in field and conjugated momenta
invariants is derived for the scalar field using the Noether's theorem
procedure.Comment: LaTeX, 6 pages, preprint of Instituto de Ciencias Nucleares, UNAM,

Identification of Long-lived Charged Particles using Time-Of-Flight Systems at the Upgraded LHC detectors
We study the impact of picosecond precision timing detection systems on the
LHC experiments' long-lived particle search program during the HL-LHC era. We
develop algorithms that allow us to reconstruct the mass of such charged
particles and perform particle identification using the time-of-flight
measurement. We investigate the reach for benchmark scenarios as a function of
the timing resolution, and find sensitivity improvement of up to a factor of
ten, depending on the new heavy particle mass.Comment: 20 pages, 13 figure
Squeezing in a 2-D generalized oscillator
A two-dimensional generalized oscillator with time-dependent parameters is
considered to study the two-mode squeezing phenomena. Specific choices of the
parameters are used to determine the dispersion matrix and analytic
expressions, in terms of standard hermite polynomials, of the wavefunctions and
photon distributions. (to be publish in the Third Workshop on Squeezed States
and Uncertainty Relations, Baltimore, USA, (August 1993))Comment: LaTeX, 5 pages, preprint of Instituto de Ciencias Nucleares, UNAM
