15. Electroweak ALP Searches at a Muon Collider

Lingfeng Li (Brown U.)

A high-energy muon collider with center-of-mass energy around and above 10 TeV is also a vector boson fusion (VBF) machine, due to the significant virtual electroweak (EW) gauge boson content of high-energy muon beams. This feature, together with the clean environment, makes it an ideal collider to search for TeV-scale axion-like particles (ALP) coupling to Standard Model EW gauge bosons,...

16. Dark Hadrons at Lifetime Frontier Experiments

Takumi Kuwahara (Peking U)

Dark hadrons are hypothetical particles which reside in the dark sector and originate from the confining gauge dynamics in the dark sector. These particles are proposed in several dark sector models, such as composite asymmetric dark matter models and strongly interacting massive particle models. The dark sector is feebly connected to our sector through dark photons which kinematically mix...

14. A search for heavy Higgs bosons decaying into vector bosons in same-sign two-lepton final states in $pp$ collisions at $\sqrt{s}=13$~TeV with the ATLAS detector

A search for heavy Higgs bosons decaying into a pair of vector bosons and produced in association with a vector boson is performed, using final states with two leptons of the same electric charge (electrons or muons), missing transverse momentum and jets. A data sample of proton-proton collisions at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the Large Hadron Collider...

8. Precise Measurements of Z+photon final states and search for anomalous neutral gauge couplings with EFT at ATLAS

Danning Liu (TDLI/SJTU)

03/08/2022, 16:00

This talk will present the latest result of precise measurement of Z+photon+jets differential cross sections and the probe of BSM new physics via anomalous neutral gauge couplings parameterized with EFT formalism at ATLAS.

17. Dark photon kinetic mixing effects for the CDF W-mass measurement

Zhi-peng Xing (TDLI)

A new $U(1)_X$ gauge boson $X$ primarily interacting with a dark sector can have renormalizable kinetic mixing with the standard model (SM) $U(1)_Y$ gauge boson $Y$. This mixing besides introduces interactions of dark photon and dark sector with SM particles, it also modifies interactions among SM particles. The modified interactions can be casted into the oblique $S$, $T$ and $U$...
