Properties of hadronic systems according to the non-extensive self-consistent thermodynamics
The non-extensive self-consistent theory describing the thermodynamics of
hadronic systems at high temperatures is used to derive some thermodynamical
quantities, as pressure, entropy, speed of sound and trace-anomaly. The
calculations are free of fitting parameters, and the results are compared to
lattice QCD calculations, showing a good agreement between theory and data up
to temperatures around 175 MeV. Above this temperature the effects of a
singularity in the partition function at To = 192 MeV results in a divergent
behaviour in respect with the lattice calculation.Comment: 10 pages, 7 figures, text modified in a few aspects. The discussion
on the connections between non-extensive and lattice quantities is modified
by the inclusion of a new figur
Systematic analysis of transverse momentum distribution and non-extensive thermodynamics theory
A systematic analysis of transverse momentum distribution of hadrons produced
in ultra-relativistic and collisions is presented. We investigate
the effective temperature and the entropic parameter from the non-extensive
thermodynamic theory of strong interaction. We conclude that the existence of a
limiting effective temperature and of a limiting entropic parameter is in
accordance with experimental data.Comment: 7 pages, XII Hadron Physics Conference, Bento Gon\c{c}alves - Brazi
HUBUNGAN ANTARA ANONIMITAS DENGAN CYBERBULLYING PADA REMAJA PENGGUNA MEDIA SOSIAL
Technological developments, including in this digital world, provide positive opportunities for humans to interact through social media. Teenagers are a community group that actively interacts through social media. In addition to positive opportunities, social media also leads to negative consequences, such as cyberbullying that occurs on social media, likely related to anonymous behaviour that refers to an individual's attempt to hide their real identity when interacting on social media. This study aimed to determine the relationship between anonymity and cyberbullying. Three hundred eighty-five active social media users aged 18 – 21 participated in this quantitative study. Active social media users were recruited based on accidental sampling. Participants filled out an anonymity scale and a cyberbullying scale. The results showed a significantly positive relationship between anonymity and cyberbullying, where the higher the level of anonymity, the higher the level of cyberbullying. Teenage boys and girls tend to use Instagram social media. In addition, most male and female participants fall into the moderate category on three aspects of anonymity (unlikability, unobservability, pseudonymity). In cyberbullying, most male participants fall into the low category in the aspect of intention. In contrast, most female participants belong to the low category regarding power imbalance and intention. The implications of different research findings based on gender can be a reference to the interaction of positive associations between anonymity and cyberbullying in adolescent social media users
Fractal aspects of hadrons
The non extensive aspects of distributions obtained in high energy
collisions are discussed in relation to possible fractal structure in hadrons,
in the sense of the thermofractal structure recently introduced. The evidences
of self-similarity in both theoretical and experimental works in High Energy
and in Hadron Physics are discussed, to show that the idea of fractal structure
of hadrons and fireballs have being under discussion for decades. The non
extensive self-consistent thermodynamics and the thermofractal structure allow
one to connect non extensivity to intermittence and possibly to parton
distribution functions in a single theoretical framework.Comment: 7 pages, ISMD2016 conferenc
