The Flavor Structure of the Excited Baryon Spectra from Lattice QCD

Robert G. Edwards, Nilmani Mathur, David G. Richards +1

Excited state spectra are calculated using lattice QCD for baryons that can be formed from $u$ , $d$ and $s$ quarks, namely the $N$ , $Δ$ , $Λ$ , $Σ$ , $Ξ$ and $Ω$ families of baryons.…

Determining the Neutrino Mass Hierarchy with INO, T2K, NOvA and Reactor Experiments

Anushree Ghosh, Tarak Thakore, Sandhya Choubey

The relatively large measured value of $θ_{13}$ has opened up the possibility of determining the neutrino mass hierarchy through earth matter effects. Amongst the current accelerat…

Looking for an Invisible Higgs Signal at the LHC

Diptimoy Ghosh, Rohini Godbole, Monoranjan Guchait +2

While the recent discovery of a Higgs-like boson at the LHC is an extremely important and encouraging step towards the discovery of the {\it complete} standard model(SM), the curre…

Determination of the Third Neutrino-Mixing Angle θ_(13) and its Implications

D. P. Roy

Till 2010 we had three unknown parameters of neutrino oscillation: the third mixing angle θ_(13), the sign of the larger mass difference Δm^(2)_(31) and the CP violating phase δ. T…

Searching the sbottom in the four lepton channel at the LHC

Diptimoy Ghosh, Dipan Sengupta

Direct searches at the Large Hadron Collider (LHC) have pushed the lower limits on the masses of the gluinos ( $g ~$ ) and the squarks of the first two generations ( $q ~$ …

Potential of optimized NOvA for large theta(13) & combined performance with a LArTPC & T2K

Sanjib Kumar Agarwalla, Suprabh Prakash, Sushant K. Raut +1

NOvA experiment has reoptimized its event selection criteria in light of the recently measured moderately large value of theta(13). We study the improvement in the sensitivity to t…

The decay constant of the holographic techni-dilaton and the 125 GeV boson

Daniel Elander, Maurizio Piai

We critically discuss the possibility that the 125 GeV boson recently discovered at the LHC is the holographic techni-dilaton, a composite state emerging from a strongly-coupled mo…

How large can the branching ratio of $B_{s} \to τ^{+} τ^{-}$ be ?

Amol Dighe, Diptimoy Ghosh

Motivated by the large like-sign dimuon charge asymmetry observed recently, whose explanation would require an enhanced decay rate of $B_{s} \to τ^{+} τ^{-}$ , we explore how large a bran…

Large mass splittings for fourth generation fermions allowed by LHC Higgs exclusion

Amol Dighe, Diptimoy Ghosh, Rohini M. Godbole +1

In the context of the Standard model with a fourth generation, we explore the allowed mass spectra in the fourth generation quark and lepton sectors as functions of the Higgs mass.…

Using Jet Substructure at the LHC to Search for the Light Higgs Bosons of the CP-Violating MSSM

Biplob Bhattacherjee, Amit Chakraborty, Dilip Kumar Ghosh +1

The CP-violating version of the Minimal Supersymmetric Standard Model (MSSM) is an example of a model where experimental data do not preclude the presence of light Higgs bosons in…

Magic Messengers in Gauge Mediation and signal for 125 GeV boosted Higgs boson

Pritibhajan Byakti, Diptimoy Ghosh

We consider a renormalizable messenger sector with magic messenger fields instead of usual SU(5) complete multiplets. We derive the soft supersymmetry breaking terms and show that…
