The Large Hadron electron Collider (LHeC) is designed to move the field of deep inelastic scattering (DIS) to the energy and intensity frontier of particle physics. Exploiting energy recovery… Expand

We argue that the process of constructing the quantum mechanical current of the Pauli equation by copying the line of argument used in the spin-0 case, i.e., the Schrodinger equation, is ambiguous.… Expand

We derive the "exact" Newtonian limit of general relativity with a positive cosmological constant Λ. We point out that in contrast to the case with Λ=0, the presence of a positive Λ in Einsteins's… Expand

In an effort to find new CP-violating phenomena in the Standard Model, we present a new type of CP asymmetries which have interesting theoretical features. We investigate the possibility of CP… Expand

We reconsider the virial theorem in the presence of a positive cosmological constant \ensuremath{\Lambda}. Assuming steady state, we derive an inequality of the form… Expand

The electromagnetic form factors of spin-1/2 particles are known, but due to historical reasons only half of them are found in many textbooks. Given the importance of the general result, its model… Expand

In this note we investigate the production of charged heavy particles via γγ fusion at high energy pp colliders. We revise previous claims that the γγ cross section is comparable to or larger than… Expand
