Dark Matter through the Higgs portal

G Arcadi, A Djouadi, M Raidal - Physics Reports, 2020 - Elsevier
We review scenarios in which the particles that account for the Dark Matter (DM) in the
Universe interact only through their couplings with the Higgs sector of the theory, the so …

What is the γγ resonance at 750 GeV?

R Franceschini, GF Giudice, JF Kamenik… - Journal of High Energy …, 2016 - Springer
A bstract Run 2 LHC data show hints of a new resonance in the diphoton distribution at an
invariant mass of 750 GeV. We analyse the data in terms of a new boson, extracting …

G Brooijmans, B Gripaios, F Moortgat… - arxiv preprint arxiv …, 2012 - arxiv.org
We present the activities of the" New Physics" working group for the" Physics at TeV
Colliders" workshop (Les Houches, France, 30 May-17 June, 2011). Our report includes new …

Vectorlike leptons at the large hadron collider

N Kumar, SP Martin - Physical Review D, 2015 - APS
We study the prospects for excluding or discovering vectorlike leptons using multilepton
events at the LHC. We consider models in which the vectorlike leptons decay to tau leptons …

The universal one-loop effective action

A Drozd, J Ellis, J Quevillon, T You - Journal of High Energy Physics, 2016 - Springer
A bstract We present the universal one-loop effective action for all operators of dimension up
to six obtained by integrating out massive, non-degenerate multiplets. Our general …

LHC-friendly minimal freeze-in models

G Bélanger, N Desai, A Goudelis, J Harz… - Journal of High Energy …, 2019 - Springer
A bstract We propose simple freeze-in models where the observed dark matter abundance
is explained via the decay of an electrically charged and/or coloured parent particle into …

[HTML][HTML] Scenarii for interpretations of the LHC diphoton excess: two Higgs doublets and vector-like quarks and leptons

A Angelescu, A Djouadi, G Moreau - Physics Letters B, 2016 - Elsevier
An evidence for a diphoton resonance at a mass of 750 GeV has been observed in the data
collected at the LHC run at a center of mass energy of 13 TeV. We explore several …

Vectorlike fermions and Higgs effective field theory revisited

CY Chen, S Dawson, E Furlan - Physical Review D, 2017 - APS
Heavy vectorlike quarks (VLQs) appear in many models of beyond the Standard Model
physics. Direct experimental searches require these new quarks to be heavy,≳ 800–1000 …

Lepton flavor violation and dilepton tails at the LHC

A Angelescu, DA Faroughy, O Sumensari - The European Physical …, 2020 - Springer
Starting from a general effective Lagrangian for lepton flavor violation (LFV) in quark-lepton
transitions, we derive constraints on the effective coefficients from the high-mass tails of the …

On the interpretation of a possible∼ 750 GeV particle decaying into γγ

J Ellis, SAR Ellis, J Quevillon, V Sanz, T You - Journal of High Energy …, 2016 - Springer
A bstract We consider interpretations of the recent∼ 3σ reports by the CMS and ATLAS
collaborations of a possible X (∼ 750 GeV) state decaying into γγ final states. We focus on …
