$\Lambda_b \to \Lambda \ell^+ \ell^-$ form factors, differential branching fraction, and angular observables from lattice QCD with relativistic $b$ quarks

open access: yes, 2016
Using $(2+1)$-flavor lattice QCD, we compute the 10 form factors describing the $\Lambda_b \to \Lambda$ matrix elements of the $b \to s$ vector, axial vector, and tensor currents. The calculation is based on gauge field ensembles generated by the RBC and

Cluster analysis and artificial neural networks in predicting energy efficiency of public buildings as a cost-saving approach

open access: yesCroatian Review of Economic, Business and Social Statistics, 2018
Although energy efficiency is a hot topic in the context of global climate change, in the European Union directives and in national energy policies, methodology for estimating energy efficiency still relies on standard techniques defined by experts in ...

The epidemiology of Leishmania donovani infection in high transmission foci in India.

open access: yes, 2010
OBJECTIVE: Visceral Leishmaniasis (VL) is highly prevalent in Bihar, India. India and its neighbours aim at eliminating VL, but several knowledge gaps in the epidemiology of VL may hamper that effort.

Metcalfe's law and log-period power laws in the cryptocurrencies market

open access: yesEconomics: Journal Articles, 2019
In this paper the authors investigate the statistical properties of some cryptocurrencies by using three layers of analysis: alpha-stable distributions, Metcalfe’s law and the bubble behaviour through the LPPL modelling.

Forecasting world trade: direct versus “bottom-up” approaches [PDF]

open access: yes
In a globalised world economy, global factors have become increasingly important to explain trade flows at the expense of country-specific determinants.

Dynamical screening away from equilibrium: hard photon production and collisional energy loss [PDF]

open access: yes, 1998
We investigate the production rate for hard real photons and the collisional energy loss in the quark-gluon plasma away from chemical equilibrium. Applying the Hard-Thermal-Loop resummation scheme away from equilibrium, we can show that Landau damping ...

Low Mass Dilepton Rate from the Deconfined Phase

open access: yes, 2010
We discuss low mass dilepton rates ($\le 1$ GeV) from the deconfined phase of QCD using both perturbative and non-perturbative models and compare with those from lattice gauge theory and in-medium hadron gas.
