Effective Leptophilic WIMPs at the e+e− collider

چکیده
A bstract We consider higher-dimensional effective (EFT) operators consisting of fermion dark matter (DM) connecting to Standard Model (SM) leptons upto dimension six. Considering all together and assuming the DM undergo thermal freeze-out, we find out relic density allowed parameter space in terms mass ( m χ ) New Physics (NP) scale (Λ) with one loop direct search constraints from XENON1T experiment. Allowed model is probed at proposed International Linear Collider (ILC) via monophoton signal for both Dirac Majorana cases, limited by centre-of-mass energy $$ \sqrt{s} s =1 TeV, where can be within {m}_{\chi }<\frac{\sqrt{s}}{2} m χ < 2 pair production occur Λ > validity EFT framework.

Collider limits on leptophilic interactions
Leptophilic interactions can only be observed at the LHC in four-lepton final states. If these interactions are mediated by a resonance in the di-leptonic channel with renormalizable couplings, the mediator must have spin 1. We study the LHC reach for such a vector boson allowing for arbitrary couplings. We find that only couplings to muons can be probed at the LHC because lepton flavor violati...
متن کاملStudying the Higgs Potential at the ee Linear Collider
The determination of the shape of the Higgs potential is needed to complete the investigation of the Higgs profile and to obtain a direct experimental proof of the mechanism of electro-weak symmetry breaking. This can be achieved, at a linear collider, by determining the Higgs triple self-coupling gHHH in the processes e e → HHZ and HHνeν̄e and, possibly, the quartic coupling. This paper summari...
متن کاملProbing the SUSY breaking scale at an ee collider
If supersymmetry is spontaneously broken at a low energy scale then the resulting gravitino will be very light. The interaction strength of the longitudinal components of such a light gravitino to e − ẽ pair then becomes comparable to that of electroweak interactions. If such a light gravitino is present it would significantly modify the crosssection for eLe − R → ẽLẽR from its MSSM value. Prec...
متن کاملReal photon structure at an ee linear collider
Previous studies of the kinematic coverage for measuring the photon structure function F γ 2 at a future 500 GeV e + e − linear collider [1,2] are updated using current estimates of luminosities and important detector parameters. The perturbative expansion for the evolution of F γ 2 is briefly recalled in view of a recent claim [3] that all existing next-to-leading order analyses of the photon ...
متن کاملProbing New Scales at a ee Linear Collider
Extending the sensitivity to New Physics beyond the anticipated reach of the Lhc is a prime aim of future colliders. This paper summarises the potential of an ee linear collider, at and beyond 1 TeV, using a realistic simulation of the detector response and the accelerator induced background. The possible LC energy-luminosity trade-offs offered in probing multi-TeV scales for new phenomena with...
