High Energy Proton-Proton collisions and Baryonium Dark Matter

O. I. Piskounova

The positive hyperon production asymmetries that have been measured at LHC are real demonstrations of string junction role in the baryon charge transfer at baryon production in HE…

Updated constraints on WIMP dark matter by radio observations of M31 -- all annihilation channels

Andrei E. Egorov

The present work derived the robust constraints on annihilating WIMP parameters utilizing new radio observations of M31, as well as new studies of its DM distribution and other pro…

On direct observation of millicharged particles at - factories and other -colliders

Dmitry Gorbunov, Dmitry Kalashnikov, Pavel Pakhlov +1

Hypothetical particles with tiny electric charges (millicharged particles or MCPs) can be produced in electron-positron annihilation if kinematically allowed. Typical searches for…

scattering at the LHC with the lepton pair production and one proton tagging

S. I. Godunov, E. K. Karkaryan, V. A. Novikov +3

Analytical formulas for the cross section of the reaction are presented. Fiducial cross sections are compared with those measured recently by the ATL…

The role of initial gluon emission in double production at central rapidities

S. P. Baranov, A. V. Lipatov, A. A. Prokhorov

We consider the process of double production in collisions at the LHC in the framework of -factorization approach. We focus on the gluon fragmentation mechanism whi…

Axion Electrodynamics in Strong Magnetic Backgrounds

Selym Villalba-Chávez, Anatoly E. Shabad, Carsten Müller

The overcritical regime of axion-electrodynamics (AED) is investigated. For magnetic fields larger than the characteristic scale linked to AED, quantum vacuum fluctuations due to a…

Relativistic composite-particle theory of the gravitational form factors of pion: quantitative results

A. F. Krutov, V. E. Troitsky

We use a version of the instant-form relativistic quantum mechanics of composite systems to obtain the gravitational form factors of the pion in a common approach to its electrowea…
