Indirect probe of electroweak-interacting particles with mono-lepton signatures at hadron colliders

Journal of High Energy Physics, 2019
Electroweak-interacting massive particles (EWIMPs) exist in a broad class of new physics models beyond the Standard Model. Searching for such particles is one of most primary goal at the LHC and future colliders.

Interference effects in dilepton resonance searches for Z′ bosons and dark matter mediators

Journal of High Energy Physics, 2020
New Z′ gauge bosons arise in many extensions of the Standard Model and predict resonances in the dilepton invariant mass spectrum. Searches for such resonances therefore provide important constraints on many models of new physics, but the resulting ...

BEYOND THE STANDARD MODEL

High Energy Physics, 2007
Review of recent developments in attempts to go beyond the Standard Model is given. We concentrate on three main unresolved problems: mechanism of electroweak symmetry breaking, expected new physics at the TeV scale (mainly SUSY) and the origin of the Dark matter.

Chiral Dynamics beyond the Standard Model [PDF]

, 2006
The SM Lagrangian without physical scalars is rewritten as the LO of a Low-Energy Effective Theory invariant under a higher non linear symmetry S_{nat} \supset SU(2)_W \times U(1)_Y.

CP Violation Beyond the Standard Model [PDF]

, 1996
We review CP violation in various extensions of the electroweak sector of the Standard Model. A particular emphasis is put on supersymmetric models. We describe the two CP problems of supersymmetry, concerning $d_N$ and $\epsilon_K$. We critically review

Lowering the scale of Pati-Salam breaking through seesaw mixing

Journal of High Energy Physics, 2021
We analyse the experimental limits on the breaking scale of Pati-Salam extensions of the Standard Model. These arise from the experimental limits on rare-meson decay processes mediated at tree-level by the vector leptoquark in the model.

b Physics Beyond the Standard Model [PDF]

, 2002
I review the signals for New Physics in CP-violating measurements in B and Lambda_b decays. I also discuss ways of identifying this New Physics, should such a signal be found.Comment: 10 pages, LaTeX, 1 figure, ps file included.

CP Violation Beyond the Standard Model [PDF]

, 2003
I review CP-violating signals of physics beyond the standard model in the B system. I examine the prospects for finding these effects at future colliders, with an emphasis on hadron machines.Comment: 11 pages, plain latex, no figures.

Physics Beyond the Standard Model

, 2009
I present a brief overview of some exciting possibilities for physics Beyond the Standard Model. I include short discussions of neutrino physics, the strong CP problem and axions, GUTs, large and warped extra dimensions, Little Higgs models and ...

Neutrinos properties beyond the Standard Model [PDF]

Nuclear Physics B - Proceedings Supplements, 1998
The present observational status of neutrino physics is sketched, with emphasis on the hints that follow from solar and atmospheric neutrino observations, as well as dark matter.
