With increasing laser intensity towards 1026W/cm2 and beyond, there are opportunities to investigate new areas of fundamental physics. These areas represent the exciting convergence of high-intensity lasers with high-energy physics. Here fundamental physics includes weakly interacting phenomena such as Dark Matter, Dark Energy, nonlinear QED effects, Higgs production and quantum vacuum studies as seen in the Homma’s section page 27.
The Dark-Fields project group within IZEST was launched with the title “Dark” to include the broad sense of something undetected by conventional experimental approaches. The methods that become available when utilizing high-intensity as well as high-energy laser fields open the possibility for the study of many new subjects.
A current search regards weakly interacting low-mass bosons as a candidate of dark fields via quantum optical observables such as four-wave mixing where the nonlinear atomic process in matter is replaced by a nonlinearity caused by a resonantly exchanged light boson in the vacuum. Preliminary experimental trials to search for the four-wave mixing process are on going at Kyoto (Advanced Research Center for Beam Science, Institute of Chemical Research, Kyoto University in Japan) and further tests are planned at INRS under the association of IZEST.
In addition to the Dark-Fields program, there are many other fundamental projects being developed within the IZEST framework and are detailed in this volume. A number of articles investigating laser particle pair production by QED effects are contained in Homma’s section (p 27) and the production of Higgs bosons through gamma-gamma collisions driven by laser-electron scattering is also mentioned.
