Constraints on Asymmetric Dark Matter Self Annihilation Cross Sections

Q. Li, Hoernisa Iminniyaz, Fangyu Liu

Abstract The evolution of the relic density for asymmetric dark matter incorporating self annihilation processes in both the shear‐dominated universe and Gauss–Bonnet braneworld is investigated. Under the same conditions where the ratio of final asymmetry to the initial asymmetry is identical, the …

Constraints on Asymmetric Dark Matter Self Annihilation Cross Sections

Q. Li, Hoernisa Iminniyaz, Fangyu Liu

We investigate the evolution of the relic density for asymmetric dark matter incorporating self annihilation processes in both the shear-dominated universe and Gauss-Bonnet braneworld. Under the same conditions where the ratio of final asymmetry to the initial asymmetry $ R \equiv Δ_{-\infty}/Δ_{\text{in}} …

Combination of searches for pair-produced leptoquarks at $\sqrt{s} = 13$ TeV with the ATLAS detector

Georges Aad, Erlend Aakvaag, B. Abbott, K. Abeling et autres

A statistical combination of various searches for pair-produced leptoquarks is presented, using the full LHC Run 2 (2015-2018) data set of $139$ fb$^{-1}$ collected with the ATLAS detector from proton-proton collisions at a centre-of-mass energy of $\sqrt{s}=13$ TeV. All possible decays of …

Search for new phenomena with top-quark pairs and large missing transverse momentum using 140 $\mathrm{fb}^{-1}$ of $pp$ collision data at $\sqrt{s}=13$ TeV with the ATLAS detector

G. Aad, Erlend Aakvaag, B. Abbott, K. Abeling et autres

A search is conducted for new phenomena in events with a top quark pair and large missing transverse momentum, where the top quark pair is reconstructed in final states with one isolated electron or muon and multiple jets. The search is performed …

Search for pair production of higgsinos in events with two Higgs bosons and missing transverse momentum in $\sqrt{s}=13$ TeV $pp$ collisions at the ATLAS experiment

G. Aad, B. Abbott, K. Abeling, Nils Julius Abicht et autres

This paper presents a search for pair production of higgsinos, the supersymmetric partners of the Higgs bosons, in scenarios with gauge-mediated supersymmetry breaking. Each higgsino is assumed to decay into a Higgs boson and a nearly massless gravitino. The search targets events …

A search for high-mass resonances in final states with hadronically decaying tau leptons and high missing transverse momentum using $pp$-collision data at $\sqrt{s} = 13~\text{TeV}$ collected by the ATLAS Detector

B. Abbott, D. C. Abbott, A. Abed Abud, K. Abeling et autres

A search for new heavy charged gauge bosons $W^{\prime}$, predicted by some extensions of the Standard Model is presented in this thesis. This analysis is based on data collected from proton-proton collisions with a center-of-mass-energy of $\sqrt{s}=13~\text{TeV}$ by the ATLAS detector. The …

Search for new particles in final states with a boosted top quark and missing transverse momentum in proton-proton collisions at $ \sqrt{s} $ = 13 TeV with the ATLAS detector

G. Aad, B. Abbott, K. Abeling, Nils Julius Abicht et autres

A search for events with one top quark and missing transverse momentum in the final state is presented. The fully hadronic decay of the top quark is explored by selecting events with a reconstructed boosted top-quark topology produced in association with large …
