Organizational Justice And Well-Being: Moderating Effects Of Power Distance And Collectivism

Kebajikan pekerja (employee’s well being) merupakan satu isu yang hangat di kalangan organisasi oleh kerana ia boleh mempengaruhi kepuasan bekerja dan boleh memberi kesan negatif kepada kesihatan fizikal dan mental pekerja sekiranya ia tidak dikawal. The employees well-being has been a growing concern amongst organizations as it would affect the employees satisfaction towards his or her jobs, and would affect an individual’s psychological and physical well being

Circular string in a Black p-brane leading to chaos

We consider a pulsating string near a non-extremal black p-brane (p=5 and p=6) and investigate the chaos in the corresponding string dynamics by examining the Fast Lyapunov indicator(FLI) and Poincare section. In our system, the energy and the charge play the role of control parameters. For generic values of these parameters, the numerical results show that the dynamics primarily fall into three modes: capture, escape to infinity, and quasiperiodic depending on the initial location (near to or far away from the black brane horizon) of the string. Finally, probing for different values of the winding number (n) the dynamics turns out to be sensitive to n. In particular, we observe the point particle (n=0) scenario to be integrable whereas at higher n the dynamics seems to be chaotic.Comment: 21 pages, 40 figure

ZZ polarization at an e+e−e^+e^- collider and properties of decay-lepton angular asymmetries

$Z$ production at an $e^+e^-$ collider, associated with production of other particles, can be an accurate source of information of details of electroweak interactions, including possible interactions beyond the standard model. We discuss from a general physical point of view the properties of the density matrix as well as lepton angular asymmetries. While most considerations will be applicable to processes of $Z$ production associated with any other particle or particles, for some discussions, we specialize to a $HZ$ final state. While many of the results can be found in earlier literature, especially for the process $e^+e^- \to HZ$, we give details of the reasoning, which are not always found. We discuss the properties of the spin density matrix under C, P and T transformations, and combinations thereof, as also the predictions of these for the corresponding leptonic asymmetries. The specific transformations P, CP, T and CPT are of special importance and we discuss the consequences of these symmetries or their absence for the leptonic asymmetries. A specific issue which has been given attention to is the role of beam polarization, and how one can infer on general grounds which asymmetries get enhanced by the use of beam polarization. Similarly, we also discuss which asymmetries would be sensitive to the measurement of tau polarization in $Z$ decay in to $\tau^+\tau^-$.Comment: 29 page

Indirect measurement of triple-Higgs coupling at an electron-positron collider with polarized beams

We examine the possibility of using single-Higgs production at an e+e− collider with polarized beams to measure, or constrain, indirectly a possible anomalous triple-Higgs coupling, which can contribute to the process via one-loop diagrams. In the dominant process e+e−→ZH, longitudinally polarized beams can lead to an improvement in the cross section by 50% for e− and e+ polarizations of −0.8 and +0.3, respectively. This corresponds to an improvement in the sensitivity to the triple-Higgs coupling of about 19% for a centre-of-mass energy of 250 GeV and an integrated luminosity of 2 ab−1. We also study the effect of longitudinal beam polarization on the sensitivity to the triple-Higgs coupling of Higgs production through the subdominant process e+e−→Hνν¯ occurring through WW fusion.by Saurabh D.

Heavy quark complex potential in a strongly magnetized hot QGP medium

We study the effect of a strong constant magnetic field, generated in relativistic heavy ion collisions, on the heavy quark complex potential. We work in the strong magnetic field limit with the lowest Landau level approximation. We find that the screening of the real part of the potential increases with the increase in the magnetic field. Therefore, we expect less binding of the Q ¯ Q pair in the presence of a strong magnetic field. The imaginary part of the potential increases in magnitude with the increase in magnetic field, leading to an increase of the width of the quarkonium state with the magnetic field. All of these effects result in the early dissociation of Q ¯ Q states in a magnetized hot quark-gluon plasmaby Balbeer Singh, Lata Thakur and Hiranmaya Mishr

Probing vorticity in heavy ion collision with dilepton production

We study the effect of vorticity present in heavy ion collisions (HICs) on the temperature evolution of hot quark-gluon plasma in the presence of spin-vorticity coupling. The initial global rotation entails a nontrivial dependence of the longitudinal flow velocity on the transverse coordinates and also develops a transverse velocity component that depends upon longitudinal coordinate. Both of these velocities leads to a 2+1 dimensional expansion of the fireball. It is observed that with the finite vorticity and spin-polarization fireball cools faster in comparison with the case without vorticity. Furthermore, we also discuss the consequence of this on thermal dilepton production.by Jitesh R. Bhatt, Hiranmaya Mishra and Balbeer Sing
