اسلام کے عبوری قوانین

Being the natural religion, Islam demands peaceful, liberal and civilized society. To achieve this goal Islam introduces two types of laws; permanent and Transitional law. Permanent law are those which are abide by every person of the Muslim society i.e Marriage laws, economic laws, political laws, Family laws, heir ship laws, social laws and other such laws. On the other hand there are some temporary or Transitional laws; i.e War laws, Divorce laws, laws for Slave or laws to end slavery, Criminal Laws (Qis┐s, Diyat, Rajam and Lashes etc), there laws are put into practice only in conditional situations. After achieving the goal these Transitional laws are no more in practice. Islam is complete code of life and gives Laws and Rules for any situation. Islam is natural and liberal religion, its laws since beginning are very much practicable and result oriented. Whenever and where ever Islamic laws have been put into practice society has got its fruits. In this article Islamic Transitional Law are briefly discussed to understand the background of transitional laws. Detail of these laws can be seen in Hadith and Fiqah books.

Lhcb and Physics Beyond the Standard Model-Some Aspects

The Standard Model of particle physics is a very well tested theory today. There are some theoretical as well as experimental deficiencies in the Standard Model which hint for theories beyond the Standard Model. Any such theory may be tested by direct observation of some new particles, predicted by the theory, at High Energy Colliders, like the Large Hadron Collider(LHC). Since there has been no such particle detected till today, we need to study these new theories under the phenomenological aspects of our known experimental results. Such studies result in constraining the free parameter space of these models. In this thesis, we use experimental results from three different experiments at the LHC, namely the ATLAS experiment, the CMS experiment and the LHC-b experiment to constrain the parameter spaces of some of these models. The models discussed in this thesis are basically constructed by making minimal extensions in scalar and gauge structures of the Standard Model. We apply constraints on these models from the flavor physics observables which are mainly coming from the rare decays of B-mesons and are measured by the particle physics experiment, LHC-beauty (LHCb). In our study we also discuss some supersymmetric extensions of the Standard Model in light of the latest results on masses of particles and their superpartners (sparticles) provided by the ATLAS and the CMS experiments. It is also seen that the supersymmetric extensions of the Standard Model can provide a suitable dark matter candidate, the neutralino, with several coannihilation scenarios while having compatibilitywithallrecentexperimentalconstraintsfrom B-physicsandthesparticles mass bounds. Direct and indirect dark matter searches by XENON1t and Fermi-LAT collaborations are also incorporated to the studies of these models by measuring the dark matter relic density as well as spin-dependent and spin-independent cross sections forsomesampledatapoints.

We have also searched how the anomaly associated with the magnetic moment of muon can be solved within the context of the supersymmetric extensions of the Standard Model, in addition to all other constraints.
