Search for drifting constants and fifth forces from precision measurements on molecules
Precision measurements of transitions between quantum levels of molecules have opened a new arena for the search of new physics. The comparison of spectral lines measured in the present epoch with those observed in fardistant galaxies at high redshift may reveal variation of fundamental constants on a cosmological time scale. Comparison between precision laboratory experiments and first princip...
متن کاملBounds on fifth forces at the sub - Å length scale
Constraints on a possible fifth-force interaction between hadrons are derived based on an analysis of results from laser precision frequency measurements of antiprotonic helium atoms, both p4He and p3He species, and from experiments on resonant formation rates of ddlþ-ions in muon-catalyzed fusion processes. A comparison is made between accurate experimental data and first-principles theoretica...
متن کاملLEP Constraints on 5-Dimensional Extensions of the Standard Model
We study minimal 5-dimensional extensions of the Standard Model, in which all or only some of the SU(2)L and U(1)Y gauge fields and Higgs bosons propagate in the fifth compact dimension. In all the 5-dimensional settings, the fermions are assumed to be localized on a 3brane. In addition, we present the consistent procedure for quantizing 5-dimensional models in the generalized Rξ gauge. Bounds ...
متن کاملساخت و آزمون کارگاهی دینامومتر اتصال سه نقطه و چرخ پنجم سرعت سنج تراکتوری
For measuring draft force and drawbar power requirements for mounted implements, precise instruments such as three-point hitch dynamometers and tractor speed measurement devices are needed. In this research, a frame-type three-point hitch dynamometer was built and evaluated. Forces applied to dynamometer are measured by three separate load cells located on a frame which can be attached to tract...
