Associated production of Higgs and single top at the LHC in presence of the SMEFT operators

Journal of High Energy Physics, 2023
We analyse the single top production in association with the Higgs at the Large Hadron Collider (LHC) using Standard Model (SM) effective operators upto dimension six.

Approximate Hermitian-Yang-Mills structures and semistability for Higgs bundles. II: Higgs sheaves and admissible structures [PDF]

, 2012
We study the basic properties of Higgs sheaves over compact K\"ahler manifolds and we establish some results concerning the notion of semistability; in particular, we show that any extension of semistable Higgs sheaves with equal slopes is semistable ...

Softly broken symmetries in the 2HDM — an invariant formulation

Journal of High Energy Physics, 2023
Soft breaking of a symmetry requires an invariance of the dimension-4 part of the Lagrangian and non-trivial variation of the lower-dimensional part. However, in general, separation between the dim-4 and lower-dimensional Lagrangian is not invariant with

τ ± νγγ and to probe the fermiophobic Higgs boson with high cutoff scales

Journal of High Energy Physics, 2023
The light fermiophobic Higgs boson h f in the type-I two-Higgs-doublet model can evade the current search programs at the LHC since its production through the quark-antiquark annihilation and gluon fusion is not feasible. The particle can be more elusive

Probing the electroweak final state in type I 2HDM at the LHC

Journal of High Energy Physics, 2023
Most of the experimental searches of the non-Standard Model Higgs boson(s) at the LHC rely on the QCD induced production modes. However, in some beyond Standard Model frameworks, the additional Higgs bosons can have fermiophobic behaviour. The type I two

Probing non-standard HVV (V = W, Z) couplings in single Higgs production at future electron-proton collider

Journal of High Energy Physics, 2022
The couplings of the Higgs boson (H) with massive gauge bosons of weak interaction (V = W, Z), can be probed in single Higgs boson production at the proposed future Large Hadron-Electron Collider (LHeC).

Discovery prospects of a light charged Higgs near the fermiophobic region of Type-I 2HDM

Journal of High Energy Physics, 2023
Determining if the SM-like Higgs is part of an extended Higgs sector is the most important question to be asked after discovery. A light charged Higgs boson with mass smaller than the sum of top and bottom quarks is naturally allowed in Type-I two Higgs ...

Primary observables for indirect searches at colliders

Journal of High Energy Physics, 2023
We consider the complete set of observables for collider searches for indirect effects of new heavy physics. They consist of SU(3)C × U(1)EM invariant interaction terms/operators that parameterize deviations from the Standard Model.

Stringent bounds on HWW and HZZ anomalous couplings with quantum tomography at the LHC

Journal of High Energy Physics, 2023
Quantum tomography provides the full reconstruction of the density matrix of a state. We use it to study the Higgs boson decay into weak gauge bosons. Anomalous couplings beyond the Standard Model can be constrained by means of observables easily defined
