Abstract Although the 125 GeV Higgs boson discovered at the LHC is often heralded as the origin of mass, it may not in fact be the origin of Yukawa couplings. In alternative models, Yukawa couplings may instead arise from a seesaw type mechanism involving the mixing of Standard Model (SM) chiral fermions with new vector-like fermions, controlled by the vacuum expectation value (VEV) of a new complex Higgs singlet field 〈Φ〉. For example, the largest third family (t, b) quark Yukawa couplings… 

$B$-anomalies in a twin Pati-Salam theory of flavour

We perform a comprehensive phenomenological analysis of the twin Pati-Salam theory of flavour, focussing on the parameter space relevant for interpreting the B-anomalies via vector leptoquark U1

Spontaneously stabilised dark matter from a fermiophobic U(1)′ gauge symmetry

Abstract We consider the possibility that dark matter is stabilised by a discrete Z2 symmetry which arises from a subgroup of a U(1)′ gauge symmetry, spontaneously broken by integer charged scalars,



FCC Physics Opportunities

We review the physics opportunities of the Future Circular Collider, covering its e+e-, pp, ep and heavy ion programmes. We describe the measurement capabilities of each FCC component, addressing the

Evidence for the associated production of the Higgs boson and a top quark pair with the ATLAS detector

A search for the associated production of the Higgs boson with a top quark pair ((tt) over barH) is reported. The search is performed in multilepton final states using a data set corresponding to a

Raising the Higgs mass with Yukawa couplings for isotriplets in vectorlike extensions of minimal supersymmetry

Extra vectorlike matter with both electroweak-singlet masses and large Yukawa couplings can significantly raise the lightest Higgs boson mass in supersymmetry through radiative corrections. I

Extra vectorlike matter and the lightest Higgs scalar boson mass in low-energy supersymmetry

The lightest Higgs scalar boson mass in supersymmetry can be raised significantly by extra vectorlike quark and lepton supermultiplets with large Yukawa couplings but dominantly electroweak-singlet

Fermion mass hierarchies from vectorlike families with an extended 2HDM and a possible explanation for the electron and muon anomalous magnetic moments

We study an extended 2 Higgs doublet model (2HDM) in which the Standard Model (SM) Yukawa interactions are forbidden due to a global U(1)′ symmetry, but may arise via mixing with vector-like

Higgs boson to γZ decay as a probe of flavor-changing neutral Yukawa couplings

With the deeper study of Higgs particle, Higgs precision measurements can be served to probe new physics indirectly. In many new physics models, vectorlike quarks ${T}_{L}$, ${T}_{R}$ occur

Quark and lepton mass and mixing with non-universal Z′ from a 5d Standard Model with gauged SO(3)

We propose a theory of quark and lepton mass and mixing with non-universal $Z'$ couplings based on a 5d Standard Model with quarks and leptons transforming as triplets under a new gauged $SO(3)$

Finding new physics without learning about it: anomaly detection as a tool for searches at colliders

The proposed strategy to search for new physics phenomena at colliders independently of the details of such new events, and the potential of semi-supervised anomaly detection techniques to extensively explore the present and future hadron colliders’ data are demonstrated.

Performance of electron and photon triggers in ATLAS during LHC Run 2

Electron and photon triggers covering transverse energies from 5  $$\text {GeV }$$ GeV to several $$\text {TeV }$$ TeV are essential for the ATLAS experiment to record signals for a wide variety of
