Top Quark Flavor Changing Couplings at a Muon Collider
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.There is growing interest in the development of a muon collider that would make it possible to produce lepton collisions at energies of several TeV. Among others, there can be significant contributions to electroweak gauge boson, Higgs boson, and top quark physics.

Probing dimension-8 SMEFT operators through neutral meson mixing
Journal of High Energy PhysicsWe investigate the impact of effective interactions of dimension-8 (dim-8) operators in the standard model effective field theory (SMEFT) on neutral meson mixing, focusing on the K 0 − K ¯ 0 $$ {K}^0-{\overline{K}}^0 $$ , B d , s − B ¯ d , s $$ {B}_{d,s}-

Revisiting CMSSM with non-universal gaugino masses under current constraints
Journal of High Energy PhysicsTo address the longstanding tension between the Constrained Minimal Supersymmetric Standard Model (CMSSM) and recent experimental data, we investigate non-universal gaugino masses within an SU(5) Grand Unified Theory (GUT) framework, focusing on the g ~ $

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

Renormalization of the SMEFT to dimension eight: Fermionic interactions I
Journal of High Energy PhysicsThis 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.

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.
