Faking ZZZ vertices at the LHC

Journal of High Energy Physics
Searches for anomalous neutral triple gauge boson couplings (NTGCs) provide important tests for the gauge structure of the standard model. At the LHC, NTGCs are searched for via the process pp → ZZ → 4l, where the two Z-bosons are on-shell. In this paper,

Coloured spin-1 states in composite Higgs models

Journal of High Energy Physics
Strong dynamics for composite Higgs models predict spin-1 resonances which are expected to be in the same mass range as the usually considered top-partners.

Renormalization of the SMEFT to dimension eight: Fermionic interactions I

Journal of High Energy Physics
This is the third of a series of works [1, 2] aimed at renormalizing the Standard Model effective field theory at one loop and to order 1/Λ4, with Λ being the new physics cut-off.

Electroweak ALP searches at a muon collider

Journal of High Energy Physics, 2022
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.

Probing axion-like particles coupling to gluons at the LHC

Journal of High Energy Physics, 2022
Assuming ALPs couple to gluons only, they can be produced via the pp → aj process and decay into two jets at the LHC. When the coupling parameter, C G ~ $$ {C}_{\overset{\sim }{G}} $$ /f a , is small, the lifetime of ALPs can be long enough leading to ...

An updated view on the ATOMKI nuclear anomalies

Journal of High Energy Physics, 2023
In view of the latest experimental results recently released by the ATOMKI collaboration, we critically re-examine the possible theoretical interpretation of the observed anomalies in terms of a new BSM boson X with mass ~ 17 MeV. To this end we employ a

Phenomenology

, 2023
Whether occupation is engaged in at an individual level, as a member of a group, or as part of community, phenomenology is most interested in the essence of the individual’s experience.

pMSSM versus complete models and the excellent prospects for top-squark discovery at HL-LHC

Journal of High Energy Physics
LHC supersymmetric (SUSY) particle search limits are usually performed within the context of simplified models and subsequently interpreted within the 19 parameter phenomenological MSSM (pMSSM) as to how many models avoid search limits for a particular ...

Constraining the four-light quark operators in the SMEFT with multijet and VBF processes at linear level

Journal of High Energy Physics
We investigate how the interference of the SM with ten four-light quark operators in the SMEFT can be constrained thanks to multijet and Z, W, γ VBF production in association with jets.

Solutions to axion electromagnetodynamics and new search strategies of sub-μeV axion

Journal of High Energy Physics, 2023
The Witten effect implies the electromagnetic interactions between axions and magnetic monopoles, and the quantum electromagnetodynamics (QEMD) properly describes interactions of electric charges, magnetic charges and photons.
