2 Motivation Shortcomings of Standard Model Motivation : Shortcomings of Standard Model SM works beautifully, explaining all experimental phenomena to date with great precision No compelling hints for deviations. Tanushree Basak (PRL) 10th PATRAS Workshop 2014 on Axions, WIMPs and WISPs 2

3 Motivation Shortcomings of Standard Model Motivation : Shortcomings of Standard Model SM works beautifully, explaining all experimental phenomena to date with great precision No compelling hints for deviations. But many questions remain unanswered: Tanushree Basak (PRL) 10th PATRAS Workshop 2014 on Axions, WIMPs and WISPs 2

4 Motivation Shortcomings of Standard Model Motivation : Shortcomings of Standard Model SM works beautifully, explaining all experimental phenomena to date with great precision No compelling hints for deviations. But many questions remain unanswered: Higgs mass is not protected by any symmetry Hierarchy Problem. SM has 19 unknown parameters whose value are to be set experimentally. No cold dark matter candidate. Neutrinos are massless in SM. Does not explain fermion mass hierarchy. It can not explain baryogenesis and leptogenesis. It does not give the gauge coupling unification at some high scale. Tanushree Basak (PRL) 10th PATRAS Workshop 2014 on Axions, WIMPs and WISPs 2

5 Motivation Extension of SM Shortcomings of SM = Provides motivation for BSM Physics In Standard Model : NO DM candidate! Tanushree Basak (PRL) 10th PATRAS Workshop 2014 on Axions, WIMPs and WISPs 3

6 Motivation Extension of SM Shortcomings of SM = Provides motivation for BSM Physics In Standard Model : NO DM candidate! Solution : Extensions of SM to accommodate a DM candidate Tanushree Basak (PRL) 10th PATRAS Workshop 2014 on Axions, WIMPs and WISPs 3

7 Motivation Extension of SM Shortcomings of SM = Provides motivation for BSM Physics In Standard Model : NO DM candidate! Solution : Extensions of SM to accommodate a DM candidate Some of the possible extensions of SM : Supersymmetric extension (Neutralino, Gravitino...) Gauge singlet scalar extension Fermion singlet and scalar singlet Gauge extension of SM Tanushree Basak (PRL) 10th PATRAS Workshop 2014 on Axions, WIMPs and WISPs 3

10 Model Scalar potential V (Φ, S) = m 2 Φ Φ + µ 2 S 2 +λ 1 (Φ Φ) 2 + λ 2 S 4 +λ 3 Φ Φ S 2 After spontaneous symmetry breaking (SSB) the two scalar fields can be written as, ( ) 0 Φ = v+φ, S = v B L + φ 2 2 with v and v B L real and positive. The mass eigenstates are linear combinations of φ and φ, and written as ( ) ( ) ( ) H1 cos α sin α φ = sin α cos α φ H 2 where, we identify H 2 as the SM-like Higgs boson with mass GeV.

22 Dark Matter Observations Lagrangian for effective interaction Spin-independent Cross-Section Effective lagrangian for spin-independent interaction : L eff = f p N3 R N 3 R pp + f n N3 R N 3 R nn where, f p,n is the hadronic matrix element. a q f p,n = q=u,d,s f (p,n) m p,n Tq a q + 2 m q 27 f (p,n) TG q=c,b,t a q m p,n m q is the effective coupling constant between DM and the quark. SI-scattering cross section of DM off a nucleon : σ scalar = 4m2 r π f 2 p,n m r is the reduced mass of the nucleon. Tanushree Basak (PRL) 10th PATRAS Workshop 2014 on Axions, WIMPs and WISPs 15

Spin-independent scattering cross-section of DM off a nucleon is maximum for cos α = 0.707, and maximum σ p depends on the value of heavy scalar mass.

28 Summary Summary We adopt the minimal U(1) B L extension of SM with an additional Z 2 -symmetry imposed. One of the right-handed neutrino, being odd uder Z 2, qualified as the DM candidate. Relic abundance of the DM is found to be consistent with the latest WMAP9 and Planck data only near scalar resonances. SI-scattering cross-section is well below the Xenon100 and LUX exclusion limits for DM mass ranging from GeV. Neutrino mass can be generated in this kind of model via Type-I seesaw mechanism.
