The Standard Model violates parity, but only by mechanisms which are invisible to Large Hadron Collider (LHC) experiments (on account of the lack of initial state polarisation or spin-sensitivity in the detectors). Nonetheless, new physical…
As the quality of experimental measurements increases, so does the need for Monte Carlo-generated simulated events - both with respect to the total amount and to their precision. In perturbative methods, this involves the evaluation of…
ILC detectors are required to have unprecedented precision. Achieving this requires significant investment for test beam activities to complete the detector R&D needed, to test prototypes and (later) to qualify final detector system…
