Gluon distribution in proton at soft and hard pp collisions
We analyze the inclusive spectra of hadrons produced in collisions at
high energies in the mid-rapidity region within the soft QCD and perturbative
QCD assuming the possible creation of the soft gluons at low intrinsic
transverse momenta . From the best description of the LHC data we found
the parametrization of the unintegrated gluon distribution which at low
is different from the one obtained within the perturbative QCD.Comment: 10 pages, 5 figures. Talk given the 5th joint International HADRON

Charged multiplicities in pp and AA collisions at LHC
The mid-rapidity charged particle multiplicities in pp and AA collisions at
LHC energies are described in the framework of a generalized eikonal model with
shadowing corrections incorporated in AA. We show that the pp data require a
Pomeron intercept close to 1.2, higher than the conventional one close to 1.1.
An energy dependence is obtained in the LHC range and beyond. The
size and centrality dependence of the AA multiplicity at TeV
is reproduced and its energy dependence is predicted.Comment: 12 pages, 4 figures, 2 tables To be published in EPJ
Belief in a zero-sum game and subjective well-being across 35 countries
This article presents a short research report on the relationship between perceived antagonism in social relations measured using the Belief in a Zero-Sum Game (BZSG) scale, life satisfaction, and positive and negative affect. Given that individuals who believe that life is like a zero-sum game are likely to perceive their daily interactions with others as unfair, we expected that individuals with high BZSG experience more negative affect and fewer positive one, resulting in a lower satisfaction with life. In addition, we examined whether country-level BZSG may play a moderating role in these associations. Data were collected from student samples (N=7146) in 35 countries. Multilevel modelling revealed that perceived social antagonism in social relations is negatively associated with satisfaction with life and that this relationship is mediated by both positive and negative affect at the individual level. The relation of individual BZSG and negative affect on satisfaction with life were weaker in societies with higher country-level BZSG, suggesting that the effects of BZSG may be less detrimental in these countries. These findings extend previous knowledge about predictors of life satisfaction and suggest that social beliefs might also be an important factor that influences subjective well-being. The contribution of the study is that the separate treatment of life satisfaction and positive and negative affect may be helpful in many research situations, particularly from a cross-cultural perspective

Measurement Invariance of Personal Well-being Index (PWI-8) across 26 Countries
The Mental Health Continuum – Short Form is a brief scale measuring positive
human functioning. The study aimed to examine the factor structure and to explore the crosscultural
utility of the MHC-SF using bifactor models and exploratory structural equation
modelling (ESEM). Method: Using multigroup confirmatory analysis (MGCFA) we examined
the measurement invariance of the MHC-SF in 38 countries (university students,
N = 8,066;
61.73% women, mean age 21.55 years). Results: MGCFA supported the cross-cultural
replicability of a bifactor structure and a metric level of invariance between student samples. The
average proportion of variance explained by the general factor was high (ECV = .66), suggesting
that the three aspects of mental health (emotional, social, and psychological well-being) can be
treated as a single dimension of well-being. Conclusion: The metric level of invariance offers
the possibility of comparing correlates and predictors of positive mental functioning across
countries; however, the comparison of the levels of mental health across countries is not possible
due to lack of scalar invariance. Our study has preliminary character and could serve as an initial
assessment of the structure of the MHC-SF across different cultural settings. Further studies on
general populations are required for extending our findings
