Impact-parameter analysis of the new TOTEM pp data at 13 TeV: black disk limit excess
A. Alkin, E. Martynov, O. Kovalenko +1
We revisit a discussion on the impact-parameter dependence of proton-proton elastic scattering amplitude with improved uncertainty calculation. This analysis allows to reveal the a…
New Test of Modulated Electron Capture Decay of Hydrogen-Like Pm Ions: Precision Measurement of Purely Exponential Decay
F. C. Ozturk, B. Akkus, D. Atanasov +92
An experiment addressing electron capture (EC) decay of hydrogen-like Pm ions has been conducted at the experimental storage ring (ESR) at GSI. The decay appears to…
Some optimal recovery problems for operators on classes of -space valued functions
V. Babenko, V. Kolesnyk, O. Kovalenko
We solve three optimal recovery problems for operators on classes of -space (which is a semilinear metric space with two additional axioms that connect the metric with the algeb…
Impact analysis of TOTEM data at the LHC: black disk limit exceeded
A. Alkin, E. Martynov, O. Kovalenko +1
We discuss the profile of the impact--parameter dependent elastic scattering amplitude. Extraction of impact-parameter dependence from the dataset with inclusion of the experimenta…
Magnetization switching by ultrashort acoustic pulses
O. Kovalenko, T. Pezeril, V. V. Temnov
It is shown theoretically that a single a few picoseconds long acoustic pulse can reverse magnetization in a magneto-strictive material Terfenol-D. Following giant magneto-elastic…
Ultrafast electron-phonon-magnon interactions at noble metal-ferromagnet interfaces
V. Shalagatskyi, O. Kovalenko, V. Shumylo +8
Ultrafast optical excitation of gold-cobalt bilayers triggers the nontrivial interplay between the electronic, acoustic, and magnetic degrees of freedom. Laser-heated electrons gen…
Can the "standard" unitarized Regge models describe the TOTEM data?
A. Alkin, O. Kovalenko, E. Martynov
The standard Regge poles are considered as inputs for two unitarization methods: eikonal and U-matrix. It is shown that only models with three input pomerons and two input odderons…
