Dark matter, millicharges, axion and scalar particles, gauge bosons, and other new physics with LDMX
Dark matter, millicharges, axion and scalar particles, gauge bosons, and other new physics with LDMX
The proposed LDMX experiment would provide roughly a meter-long region of instrumented tracking and calorimetry that acts as a beam stop for multi-GeV electrons in which each electron is tagged and its evolution measured. This would offer an unprecedented opportunity to access both collider-invisible and ultrashort-lifetime decays of new particles …
