Next-to-Next-to-Leading Order QCD Corrections in Models of TeV-Scale Gravity
Daniel de Florian, Maguni Mahakhud, Prakash Mathews +2
We compute the next-to-next-to-leading order QCD corrections to the graviton production in models of TeV-scale gravity, within the soft-virtual approximation. For the Arkani-Hamed,…
Liouville Numbers and Schanuel's Conjecture
K. Senthil Kumar, R. Thangadurai, M. Waldschmidt
In this paper, using an argument of P. Erdos, K. Alniacik and E. Saias, we extend earlier results on Liouville numbers, due to P. Erdos, G.J. Rieger, W. Schwarz, K. Alniacik, E. Sa…
Liouville numbers, Liouville sets and Liouville fields
K. Senthil Kumar, R. Thangadurai, M. Waldschmidt
Following earlier work by E.Maillet 100 years ago, we introduce the definition of a Liouville set, which extends the definition of a Liouville number. We also define a Liouville fi…
Radio frequency spectroscopy of the attractive Hubbard model in a trap
Sanjoy Datta, Viveka Nand Singh, Pinaki Majumdar
Attractive interaction between fermions can lead to pairing and superfluidity in an optical lattice. In contrast to the `continuum', on a lattice the trap induced density variation…
Universal Extra-Dimensional models with boundary terms: Probing at the LHC
Anindya Datta, Ujjal Kumar Dey, Amitava Raychaudhuri +1
In universal extra-dimensional models a conserved Z_2 parity stabilizes the lightest Kaluza-Klein particle, a dark-matter candidate. Boundary-localized kinetic terms, in general, d…
Phase Structure of Higher Spin Black Holes
Abhishek Chowdhury, Arunabha Saha
We revisit the study of the phase structure of higher spin black holes carried out in arXiv using the "canonical formalism". In particular we study the low as well as h…
