Multiplicity Fluctuation

This paper reports a detailed study on self-affine behavior of multiplicity fluctuation in the pionization process at relativistic and ultrarelativistic nuclear collisions. The study was performed over a wide range of energy from 2.1–200 AGeV. The data used are 16 O-AgBr interactions at 2.1 AGeV and 60 AGeV, 32 S-AgBr interactions at 200 AGeV, 24 Mg-AgBr , and 12 C-AgBr interactions at 4.5 AGeV. All these data show a clear evidence of self-affine pion production over the entire energy regime.

Multiplicity Fluctuation

The relation between multiplicity and transverse energy in high energy h-h and A-A collisions is investigated using a Monte Carlo generator of nondiffractive processes. The width of multiplicity fluctuation D/<n> for fixed E⊥ is found to be small and approximately constant for a wide range of E⊥.

The need for modernization of the existing energy sector is driven by globally increasing energy demand, rising carbon emissions, global warming, and climate change. The world tends towards the sustainable and more environmentally friendly energy sector that will meet future energy demands by reducing the usage of raw and non-renewable materials and resources and decreasing energy consumption and pollution. Nanotechnology, as one of the key technologies of the 21st Century, holds the potential to revolutionize the entire energy sector, contributing to the development of more efficient and sustainable energy systems. The implementation of nanotechnology in the energy sector is in the various stages of research, development, and deployment. Nanotechnology’s solutions and approaches can help create innovative ways to produce, change, distribute, store and consume energy. This paper attempts to summarize some of the current nanotechnology applications in energy sector, emphasizing the associated benefits as well as risks and concerns. Present nanotechnology-based solution and approaches used in the energy sector confirms nanotechnology's potential to revolutionize the entire energy sector. Alongside the growing use of nanomaterials and nanoproducts, uncertainties on the nanotechnology potentially harmful influence on the environment, health, and safety rise as well, representing a main concern related to nanotechnology applications. In addition to the technological feasibility of the nanotechnology implementation in the energy sector, a wide range of other conditions, such as political, economical and social, influence the rate of implementation and acceptance of nanotechnological innovations in the energy sector.

Multiplicity Fluctuation

The first estimation of the isothermal compressibility (kT) of matter is presented for a wide range of collision energies from √sNN = 7.7 GeV to 2.76 TeV. kT is estimated with the help of event-byevent charged particle multiplicity fluctuations from experiment. Dynamical fluctuations are extracted by removing the statistical fluctuations obtained from the participant model. kT is also estimated from event generators AMPT, UrQMD, EPOS and a hadron resonance gas model. The values of isothermal compressibility are estimated for the Large Hadron Collider (LHC) energies with the help of the event generators.
