DESCRIPTION:Speakers: Dr. FUNATSU\, Shuichiro (Central China Normal Univer
 sity)\nThe signals of the SO(5) × U(1) gauge-Higgs unification model at t
 he International Linear Collider are studied. \nIn this model\, Kaluza-Kle
 in modes of the neutral gauge bosons affect fermion pair productions. \nTh
 e deviations of the forward-backward asymmetries of the $e^+ e^- to \\bar{
 b}b\, \\bar{t}t$ processes from the standard model predictions are clearly
  seen by using polarised beams. \nThe deviations of these values are predi
 cted for two cases\, the bulk mass parameters of quarks are positive and n
 egative case.\n\nhttp://indico.fuw.edu.pl/contributionDisplay.py?contribId

SUMMARY:Extended Scalar Sectors at CLIC

DESCRIPTION:Speakers: Mr. AZEVEDO\, Duarte (Centro de Física Teórica e C
 omputacional\, Universidade de Lisboa.)\nThe phenomenology of several Beyo
 nd the Standard Model (SM) extensions that include extended Higgs sectors 
 will be presented. The models discussed are: the SM extended by a complex 
 singlet field (CxSM)\, the 2-Higgs-Doublet Model with a CP-conserving (2HD
 M) and a CP-violating (C2HDM) scalar sector\, the singlet extension of the
  2-Higgs-Doublet Model (N2HDM)\, and the Next-to-Minimal Supersymmetric SM
  extension (NMSSM). All the above models have at least three neutral scala
 rs\, with one being the 125 GeV Higgs boson. This common feature allows us
  to compare the production and decay rates of the other two scalars and th
 erefore to compare their behaviour at future electron-positron colliders. 
 Using predictions on the expected precision of the 125 GeV Higgs boson cou
 plings at these colliders we are able to obtain the allowed admixtures of 
 either a singlet or a pseudoscalar to the observed 125 GeV scalar\, how mu
 ch CP-violating can the Yukawa couplings have\, among other. Therefore\, e
 ven if no new scalar is found\, the expected precision at future electron-
 positron colliders\, such as CLIC\, will certainly contribute to a clearer
  picture of the nature of the discovered Higgs boson.\n\nhttp://indico.fuw

SUMMARY:Lepton number violation from right-sneutrinos through the heavy Hi

DESCRIPTION:Speakers: Dr. WALTARI\, Harri (Rutherford Appleton Laboratory 
 &amp\; Univ. Southampton)\nWe explore the possibility of observing lepton 
 number violation originating from the sneutrino sector at the LHC. In the 
 NMSSM extended with right-handed neutrinos the right-sneutrinos can have a
  tiny decay width so that the lepton number violating terms can generate a
  sizable effect before the sneutrino decays. We explore the possibility to
  produce the right-sneutrinos through the heavy Higgs portal and generate 
 a same-sign dilepton + MET signature.\n\nhttp://indico.fuw.edu.pl/contribu
