The measurement of the Higgs quartic coupling modifier between a boson pair and vector pair, ?2V, is expected to be achieved from vector-boson fusion (VBF) production pair. However, this process involves another unmeasured parameter, trilinear self-coupling ??. A sensitivity analysis should target both parameters. Since LHC cannot avoid gluon pollution, which becomes severe for non-SM ??, an el...

A bstract We study capability of the ILC beam dump experiment to search for new physics, comparing performance electron and positron dumps. The dark photon, axion-like particles, light scalar bosons are considered as physics scenarios, where all important production mechanisms included: electron-positron pair-annihilation, Primakoff process, bremsstrahlung productions. find that has higher sens...

The combination of density-functional theory with other approaches to the many-electron problem through the separation of the electron-electron interaction into a short-range and a long-range contribution is a promising method, which is raising more and more interest in recent years. In this work some properties of the corresponding correlation energy functionals are derived by studying the ele...
