Smuon in the NMSSM confronted with the muon g–2 anomaly and SUSY searches
2023年
Motivated by recent supersymmetry(SUSY)search results,which prefer most SUSY particles to be heavy,and the muon g–2 anomaly,which prefers colorless SUSY particles to be light,we explore the status of a light smuon(the SUSY partner of a left-handed muon lepton)in the next-to-minimal supersymmetric standard model(NMSSM).Assuming colored SUSY particles to be heavy,and considering numerous experimental constraints,including muon g-2,SUSY searches,and dark matter,we scan the parameter space in the NMSSM with Z3-symmetry and check the status of colorless SUSY particles and their possible mass order,paying special attention to the smuon.After calculations and discussions,we find that the surviving samples can be divided into several scenarios,where the mass region and decay information of the smuon are given.Overall,the smuon mass can be approximately 0.1~1.8 TeV.These results may be useful for smuon searches at the LHC and future colliders.

Nuclear 0ν2βdecays in B-L symmetric SUSY model and in TeV scale left–right symmetric model
2022年
In this paper,we take the B-L supersymmetric standard model(B-LSSM)and TeV scale left–right symmetric model(LRSM)as two representations of the two kinds of new physics models to study the nuclear neutrinoless double beta decays(0ν2β)so as to see the senses onto these two kinds of models when the decays are taken into account additionally.Within the parameter spaces allowed by all the existing experimental data,the decay half-life of the nucleus^(76)Ge and^(136)Xe,T_(12)^(0ν)(^(76)Ge,^(136)Xe),is precisely calculated and the results are presented properly.Based on the numerical results,we conclude that there is greater room for LRSM type models than for B-LSSM type models in foreseeable future experimental observations on the decays.

Low energy SUSY confronted with new measurements of W-boson mass and muon g-2被引量:2
2022年
The new CDF II measurement of W-boson mass shows a 7σdeviation from the standard model(SM)prediction,while the recent FNAL measurement of the muon g-2 shows a 4.2σdeviation(combined with the BNL result)from the SM.Both of them strongly indicate new physics beyond the SM.In this work,we study the implication of both measurements on low energy supersymmetry.With an extensive exploration of the parameter space of the minimal supersymmetric standard model(MSSM),we find that in the parameter space allowed by current experimental constraints from colliders and dark matter detections,the MSSM can simultaneously explain both measurements on the edge of 2σlevel,taking theoretical uncertainties into consideration.The favored parameter space,characterized by a compressed spectrum between bino,wino and stau,with the stop being around 1 TeV,may be covered in the near future LHC searches.

Impact of LHC probes of SUSY and recent measurement of(g-2)_μon Z_(3)-NMSSM
2022年
It is well known that excessively heavy supersymmetric particles(sparticles)are disfavored to explain the(g−2)_(μ) anomaly,but some people overlook that moderately light sparticles are also disfavored by the LHC probes of supersymmetry.We take the Next-to-Minimal Supersymmetric Standard Model as an example to emphasize the latter point.It is found that,if the theory is required to explain the anomaly at 2σlevel and meanwhile keep consistent with the LHC results,the following lower bounds may be set:tanβ&20,|M_(1)|&275 GeV,M_(2)&300 GeV,μ&460 GeV,m_(μL)&310 GeV,and m_(μR)&350 GeV,where M_(1)and M_(2)denote gaugino masses,μrepresents the Higgsino mass,and m_(μL)and m_(μR)are the mass of Smuons with L and R denot-ing their dominant chiral component.This observation has significant impacts on dark matter(DM)physics,e.g.,the popular Z-and Higgs-funnel regions have been excluded,and the Bino-dominated neutralino DM has to co-annihilate with the Wino-dominated electroweakinos(in most cases)and/or Smuons(in few cases)to obtain the correct density.It is also inferred that these conclusions keep valid for the Minimal Supersymmetric Standard Model since the underlying physics for the bounds are the same.

A private SUSY 4HDM with FCNC in the up-sector
2021年
We present a SUSY model with four Higgs doublets of the"private type,"in which all fermion types(up,down,and charged leptons)obtain their masses from a different Higgs doublet H_f(f=u_1,d,e) .The conditions for anomaly cancellation imply that the remaining Higgs doublet of the model( H_(u_2) )must have the same hypercharge as H_(u_1) ,and thus,can only couple to up-type quarks,which opens the possibility to have FCNCs only in this sector.We study the Lagrangian of the model,and in particular,the Higgs potential,to identify the Higgs mass-eigenstates and their interactions;for the Yukawa matrices,we consider the four-texture case.We obtain constraints on the model parameters by using LHC measurements on the properties of the 125 GeV Higgs boson(h),and identify viable regions of the parameter space.Subsequently,these constraints are used to evaluate the prospects for detecting the FCNC decay mode t→ch at the future high-luminosity(HL)option for the LHC,which are compared with current limits from LHC-run2.Moreover,we evaluate the FCNC decay of the next heavier Higgs boson H_(2)→tc ,which can typically reach BR(H_2→tc)≈(10^(-4)-10^(-5)) .The search for the signal at HL-LHC is also studied,and it is found that it may be detectable for specific regions of the model parameter space.
