Testing leptogenesis at the LHC and future muon colliders: a scenario
Wei Liu, Ke-Pan Xie, Zihan Yi
If the masses of at least two generations of right-handed neutrinos (RHNs) are near-degenerate, the scale of leptogenesis can be as low as 100 GeV. In this work, we study pr…
Probing Higgs exotic decay at the LHC with machine learning
Sunghoon Jung, Zhen Liu, Lian-Tao Wang +1
We study the tagging of Higgs exotic decay signals using different types of deep neural networks (DNNs), focusing on the associated production channel followed by Higgs d…
Probing superheavy dark matter with gravitational waves
Ligong Bian, Xuewen Liu, Ke-Pan Xie
We study the superheavy dark matter (DM) scenario in an extended model, where one generation of right-handed neutrino is the DM candidate. If there is a new lighter ste…
Primordial black holes from a cosmic phase transition: The collapse of Fermi-balls
Kiyoharu Kawana, Ke-Pan Xie
We propose a novel primordial black hole (PBH) formation mechanism based on a first-order phase transition (FOPT). If a fermion species gains a huge mass in the true vacuum, the co…
Probing the electroweak symmetry breaking with Higgs production at the LHC
Ke-Pan Xie, Bin Yan
The electroweak symmetry breaking (EWSB) mechanism is still an undecided question in particle physics. We propose to utilize the single top quark and Higgs associated production ($…
Probing electroweak phase transition with multi-TeV muon colliders and gravitational waves
Wei Liu, Ke-Pan Xie
We study the complementarity of the proposed multi-TeV muon colliders and the near-future gravitational wave (GW) detectors to the first order electroweak phase transition (FOEWPT)…
