An explicit realization of fractional statistics in one dimension

S. Sree Ranjani, P. K. Panigrahi, A. K. Kapoor +1

An explicit realization of anyons is provided, using the three-body Calogero model. The fact that in the coupling domain, $- 1/4 < g < 0$ , the angular spectrum can have a band structure…

Explaining B \to K pi anomaly with non-universal Z' boson

R. Mohanta, A. K. Giri

We study the effect of non-universal $Z^{'}$ boson in the decay modes $B \to K π$ . In the standard model these modes receive dominant contributions from $b \to s$ QCD penguins. Theref…

$B_{s}^{0} - B ˉ_{s}^{0}$ mixing and $b \to s$ transitions in isosinglet down quark model

R. Mohanta, A. K. Giri

The recent observation of the mass difference in $B_{s}$ system seems to be not in complete agreement with the corresponding standard model value. We consider the model with an extra…

Diphoton signals in theories with large extra dimensions to NLO QCD at hadron colliders

M. C. Kumar, Prakash Mathews, V. Ravindran +1

We present a full next-to-leading order (NLO) QCD corrections to diphoton production at the hadron colliders in both standard model and ADD model. The invariant mass and rapidity d…

Dvali-Gabadadze-Porrati Cosmology in Bianchi I brane

Rizwan Ul Haq Ansari, P K Suresh

The dynamics of Dvali-Gabadadze-Porrati Cosmology (DGP) braneworld with an anisotropic brane is studied. The Friedmann equations and their solutions are obtained for two branches o…

Two elementary proofs of the Wigner theorem on symmetry in quantum mechanics

R. Simon, N. Mukunda, S. Chaturvedi +1

In quantum theory, symmetry has to be defined necessarily in terms of the family of unit rays, the state space. The theorem of Wigner asserts that a symmetry so defined at the leve…

The fourth family: a simple explanation for the observed pattern of anomalies in B-CP asymmetries

Amarjit Soni, Ashutosh Kumar Alok, Anjan Giri +2

We show that a fourth family of quarks with $m_{t^{'}}$ in the range of (400 - 600) GeV provides a rather simple explanation for the several indications of new physics that have been…

Squeezed States and Affleck Dine Baryogenesis

K. V. S. Shiv Chaitanya, Bindu A Bambah

Quantum fluctuations in the post inflationary Affleck-Dine baryogenesis model are studied. The squeezed states formalism is used to give evolution equations for the particle and an…

Construction of localized atomic wave packets

S. Sree Ranjani, P. K. Panigrahi, A. K. Kapoor

It is shown that highly localized solitons can be created in lower dimensional Bose-Einstein condensates (BEC), trapped in a regular harmonic trap, by temporally varying the trap f…

Bounds on large extra dimensions from photon fusion process in SN1987A

V. H. Satheeshkumar, P. K. Suresh

The constraint on the ADD model of extra dimensions coming from photon annihilation into Kaluza-Klein graviton in supernova cores is revisited. In the two photon process for a cons…

Unparticles in diphoton production to NLO in QCD at the LHC

M. C. Kumar, Prakash Mathews, V. Ravindran +1

We compute to next-to-leading order in QCD the tensor unparticle contribution to the diphoton production at the LHC, wherein the unparticle sector is a consequence of (a) scale inv…

Signature of new physics in B -> phi pi decay

B. Mawlong, R. Mohanta, A. K. Giri

We investigate the effect of an extra fourth quark generation and FCNC mediated $Z$ and $Z^{'}$ bosons on the rare decay mode $B^{-} \to ϕ π^{-}$ . In the standard model, this mode receives…

Twisted Statistics in kappa-Minkowski Spacetime

T. R. Govindarajan, Kumar S. Gupta, E. Harikumar +2

We consider the issue of statistics for identical particles or fields in kappa-deformed spaces, where the system admits a symmetry group G. We obtain the twisted flip operator comp…

Aspects of Noncommutative Scalar/Tensor Duality

K. M. Ajith, E. Harikumar, Victor O. Rivelles +1

We study the noncommutative massless Kalb-Ramond gauge field coupled to a dynamical U(1) gauge field in the adjoint representation together with a compensating vector field. We der…
