Autor: S. I. Godunov, E. K. Karkaryan, V. A. Novikov, A. N. Rozanov, M. I. Vysotsky, E. V. Zhemchugov

Publikováno v: European Physical Journal C: Particles and Fields, Vol 82, Iss 11, Pp 1-8 (2022)

Abstract Analytical formulas for the cross section of the reaction $$pp \rightarrow p + \ell ^+ \ell ^- + X$$ p p → p + ℓ + ℓ - + X are presented. Fiducial cross sections are compared with those measured recently by the ATLAS collaboration.

Production of heavy charged particles in proton-proton ultraperipheral collisions at the Large Hadron Collider: survival factor

Autor: S. I. Godunov, V. A. Novikov, A. N. Rozanov, M. I. Vysotsky, E. V. Zhemchugov

Publikováno v: Journal of High Energy Physics, Vol 2021, Iss 10, Pp 1-17 (2021)

Abstract Ultraperipheral collisions of high energy protons are a source of approximately real photons colliding with each other. Photon fusion can result in production of yet unknown charged particles in very clean events. The cleanliness of such an

Long-lived Charged Particles in Ultraperipheral Collisions at the LHC

Autor: E. V. Zhemchugov

Publikováno v: Physics of Atomic Nuclei. 83:1714-1717

Production of long-lived charged particles (LLCP) with the masses of the order of 100 GeV in ultraperipheral collisions (UPC) of protons or heavy ions at the Large Hadron Collider (LHC) is considered. A new approach for the search of such particles u

LHC as a photon-photon collider: Bounds on ΓX→γγ

Autor: M. I. Vysotsky, E. V. Zhemchugov, S. I. Godunov, Alexandre Rozanov, V. A. Novikov, E. K. Karkaryan

Publikováno v: Physical Review

In the relatively recent CMS data, there is a hint on the existence of a resonance with the mass 28 GeV decaying to a μ+μ− pair and produced in association with a b quark jet and a second jet. Such a resonance should also couple to photons throug

Looking for chiral anomaly in pion photoproduction on kaons

Autor: M. I. Vysotsky, E. V. Zhemchugov

Publikováno v: Physics of Particles and Nuclei. 48:956-959

In an experiment currently being performed at the Institute for High Energy Physics, Serpukhov, Russia, a beam of charged kaons is directed on a copper target. In the electromagnetic field of the target nuclei, two reactions occur: K+γ → K+π0 and

We propose a model-independent approach for the search of charged long-lived particles produced in ultraperipheral collisions at the LHC. The main idea is to improve event reconstruction at ATLAS and CMS with the help of their forward detectors. Dete

Dimuon resonance near 28 GeV and muon anomaly

Autor: S. I. Godunov, M. I. Vysotsky, Viktor A Novikov, E. V. Zhemchugov

We discuss if the resonance recently observed by CMS can be responsible for the deviation of the experimentally measured muon anomalous magnetic moment from the theoretical prediction.

Double Higgs boson production in the models with isotriplets

Autor: E. V. Zhemchugov, M. I. Vysotsky, S. I. Godunov

Publikováno v: Physics of Atomic Nuclei. 78:1493-1496

The enhancement of double Higgs boson production in the extensions of the Standard Model with extra isotriplets is studied. It is found that in see-saw type II model decays of new heavy Higgs can contribute to the double Higgs production cross sectio
