distributions in Standard Model at large recoil
Diganta Das, Bharti Kindra, Girish Kumar +1
We study the rare decay in the Standard Model and beyond. Working in the transversity basis, we exploit the relations between the heavy-to…
Transport properties of the classical Toda chain: effect of a pinning potential
Abhishek Dhar, Aritra Kundu, Joel L. Lebowitz +1
We consider energy transport in the classical Toda chain in the presence of an additional pinning potential. The pinning potential is expected to destroy the integrability of the s…
Investigation of Thermodynamic Properties of Cu(NH3)4SO4.H2O, a Heisenberg Spin Chain Compound
Tanmoy Chakraborty, Harkirat Singh, Dipanjan Chaudhuri +3
Detailed experimental investigations of thermal and magnetic properties are presented for Cu(NH3)4SO4.H2O, an ideal uniform Heisenberg spin half chain compound. A comparison of the…
Towards a constructive formalization of Perfect Graph Theorems
Abhishek Kr Singh, Raja Natarajan
Interaction between clique number and chromatic number of a graph is a well studied topic in graph theory. Perfect Graph Theorems are probably the most important re…
Flocking of Active Particles in a Turbulent Flow
Anupam Gupta, Amal Roy, Arnab Saha +1
We investigate the effect of cooperative interactions in an ensemble of microorganisms, modelled as self-propelled disk-like and rod-like particles, in a three-dimensional turbulen…
Measurements of branching fraction and direct asymmetry in and a search for
The Belle Collaboration, A. B. Kaliyar, P. Behera +197
We study charmless hadronic decays of charged mesons to the final states and using a data sample that cont…
A VLA-GMRT Look at 11 Powerful FR II Quasars
S. Vaddi, P. Kharb, R. A. Daly +5
We present results from 1.4 and 5 GHz observations at matched resolution with the Karl G. Jansky Very Large Array (VLA) of 11 powerful 3C FR II quasars. We examine the 11 quasars a…
[CII] 158 Micron Emission from z~4 HI Absorption-Selected Galaxies
Marcel Neeleman, Nissim Kanekar, J. Xavier Prochaska +2
We report on a search for the [CII] 158 micron emission line from galaxies associated with four high-metallicity damped Ly-alpha absorbers (DLAs) at z ~ 4 using the Atacama Large M…
Partial Function Extension with Applications to Learning and Property Testing
Umang Bhaskar, Gunjan Kumar
In partial function extension, we are given a partial function consisting of points from a domain and a function value at each point. Our objective is to determine if this part…
Generating an equidistributed net on a unit n-sphere using random rotations
Somnath Chakraborty, Hariharan Narayanan
We develop a randomized algorithm (that succeeds with high probability) for generating an -net in a sphere of dimension n. The basic scheme is to pick …
Observatory science with eXTP
Jean J. M. in 't Zand, Enrico Bozzo, Jinlu Qu +181
In this White Paper we present the potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission for studies related to Observatory Science targets. These include flaring s…
Accretion in Strong Field Gravity with eXTP
Alessandra De Rosa, Phil Uttley, Lijun Gou +99
In this paper we describe the potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission for studies related to accretion flows in the strong field gravity regime around…
Dense matter with eXTP
Anna L. Watts, Wenfei Yu, Juri Poutanen +73
In this White Paper we present the potential of the Enhanced X-ray Timing and Polarimetry (eXTP) mission for determining the nature of dense matter; neutron star cores host an extr…
A note on fierce ramification
Hélène Esnault, Lars Kindler, Vasudevan Srinivas
We show that bounding ramification at infinity bounds fierce ramification. This answers positively a question of Deligne posed to the first named author.
Statistical properties of worm algorithms for two dimensional frustrated Ising models
Geet Rakala, Kedar Damle, Deepak Dhar
We study the distribution of lengths and other statistical properties of worms constructed by Monte Carlo worm algorithms in the power-law three-sublattice ordered phase of frustra…
Searches for Continuous Gravitational Waves from Fifteen Supernova Remnants and Fomalhaut b with Advanced LIGO
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1129
We describe directed searches for continuous gravitational waves from sixteen well localized candidate neutron stars assuming none of the stars has a binary companion. The searches…
