The Compact Linear Collider (CLIC) is a mature option for the future of high energy physics. It combines benefits clean environment $e^+e^-$ colliders with operation at centre-of-mass energies, allowing to probe scales beyond reach Large Hadron (LHC) many scenarios new This places CLIC project privileged spot in between precision and frontiers, capabilities that will significantly extend knowledge on both fronts end LHC era. In this report we review revisit potential search, directly...
Energy correlators are theoretically simple and physically intuitive observables that bridge experimental theoretical particle physics. They have for example enabled the most precise jet substructure determination of strong coupling constant to date, recent proposals suggest they may be used precisely determine top quark mass with calculable, small uncertainties. However, existing energy all measure correlations in angles between particles, from which other such as must inferred through...
We initiate the study of exotic Higgs decays to long-lived particles (LLPs) at proposed future lepton colliders, focusing on scenarios with displaced hadronic final states. Our analysis entails a realistic tracker-based search strategy involving reconstruction secondary vertices and imposition selection cuts appropriate for eliminating largest irreducible backgrounds. The projected sensitivity is broadly competitive that LHC potentially superior lower LLP masses. In addition forecasting...
A bstract We assess the current coverage and future discovery potential of LHC searches for heavy Higgs bosons decaying into long-lived particles (LLPs), focusing primarily on production pairs LLPs with hadronic final states. These signatures are generic in dark sectors where a scalar decays lighter states which subsequently mix Standard Model Higgs. show that handful existing analyses provide broad LLP decay lengths ranging from millimeters to tens meters, explore complementarity between...
A bstract Jet grooming is an important strategy for analyzing relativistic particle collisions in the presence of contaminating radiation. Most jet techniques introduce hard cutoffs to remove soft radiation, leading discontinuous behavior and associated experimental theoretical challenges. In this paper, we Pileup Infrared Radiation Annihilation (P iranha ), a paradigm continuous that overcomes discontinuity infrared sensitivity hard-cutoff procedures. We motivate P from perspective optimal...
Energy correlators have recently come to the forefront of jet substructure studies at colliders due their remarkable properties: they naturally separate physics different scales, are robust contamination from soft radiation, and offer a direct connection with quantum field theory. The current parametrization used for energy correlators, however, is based on redundant pairwise angles complex phase space restrictions. In this Letter, we introduce new that features simpler structure preserves...
