Linear Collider Workshop 2000 Summary [PDF]
, 2001 We summarize some of the main physics questions that will serve to define the linear e+e- collider program, and comment on issues that confront the world community in making such a collider a reality.Comment: 16 pp, Summary of Linear Collider Workshop ...

Cutting rule for cosmological collider signals: a bulk evolution perspective [PDF]
Journal of High Energy Physics, 2021 We show that the evolution of interacting massive particles in the de Sitter bulk can be understood at leading order as a series of resonant decay and production events.

VINCIA for hadron colliders [PDF]
The European Physical Journal C, 2016 We present the first public implementation of antenna-based QCD initial- and final-state showers. The shower kernels are $2\to 3$ antenna functions, which capture not only the collinear dynamics but also the leading soft (coherent) singularities of QCD matrix elements.

Journal of High Energy Physics, 2023 Abstract We start by observing that the light-ray operators featured in the conformal collider literature are celestial primaries. This allows us to rephrase the corresponding 4D CFT correlators as probing a conformally soft matter sector of the 2D celestial CFT (CCFT). To demonstrate the utility of this perspective we show how the

Journal of High Energy Physics, 2019 A recent study [1] has shown that a simplified model predicting a heavy scalar of mass 270 GeV (H ) that decays to a Standard Model (SM) Higgs boson in association with a scalar singlet of mass 150 GeV (S) can accommodate several anomalous multi-lepton ...

Excess of Soft Dielectrons and Photons
Universe, 2020 Spectra of unbound electron–positron pairs (dielectrons, in brief) and photons from decays of parapositronia produced in ultraperipheral collisions of electrically charged objects are calculated.

Probing the RK(*) anomaly at a muon collider [PDF]
Physical Review D, 2021 The LHCb measurements of the $\mu / e$ ratio in $B \to K \ell \ell$ decays $(R_{K^{}})$ indicate a deficit with respect to the Standard Model prediction, supporting earlier hints of lepton universality violation observed in the $R_{K^{(*)}}$ ratio ...

Dark matter in the Randall-Sundrum model with non-universal coupling
Journal of High Energy Physics, 2019 We consider simplified dark matter models (DM) interacting gravitationally with the standard model (SM) particles in a Randall-Sundrum (RS) framework. In this framework, the DM particles interact through the exchange of spin-2 Kaluza-Klein (KK) gravitons

Learning from many collider events at once [PDF]
Physical Review D, 2021 There have been a number of recent proposals to enhance the performance of machine learning strategies for collider physics by combining many distinct events into a single ensemble feature.
