For the periodic sphaleron potential in the electroweak theory, we nd the one- dimensional time-independent Schrodinger equation with the Chern-Simons number as the coordinate, construct the Bloch wave function and determine the correspond- ing conducting (pass) band structure. We show that the baryon-lepton number violating processes can take place without the exponential tunneling suppression (at zero temperature) at energies around and above the barrier height (sphaleron en- ergy) at 9.0 TeV…

Role of Bloch waves in baryon-number violating processes

In the Bloch-wave approach to estimate the baryon-number-violating scattering cross section in the standard electroweak theory in the laboratory, we clarify the relation between the single sphaleron

BaryoGEN, a Monte Carlo generator for sphaleron-like transitions in proton-proton collisions

A bstractSphaleron and instanton solutions of the Standard Model provide violation of baryon and lepton numbers and could lead to spectacular events at the LHC or future colliders. Certain models of

Baryon Number Violating Scatterings in Laboratories

Earlier estimates have argued that the baryon number violating scattering cross-section in the laboratory is exponentially small so it will never be observed, even for incoming 2-particle energy well

Search for sphalerons in the e μ final state at √ s = 13 TeV with the CMS experiment

This thesis is concerned with the first ever search for electroweak sphalerons in the electron-muon final state in proton-proton collisions at the LHC at a centre-of-mass energy of √ s = 13 TeV. The

B+L violation at colliders and new physics

A bstractChiral electroweak anomalies predict baryon (B) and lepton (L) violating fermion interactions, which can be dressed with large numbers of Higgs and gauge bosons. The estimation of the total

On the phenomenology of sphaleron-induced processes at the LHC and beyond

Abstract We investigate the phenomenological aspects of non-perturbative baryon- and lepton-number-violating processes at hadron colliders. Such processes, induced by instan- ton/sphaleron

Search for sphalerons in proton-proton collisions

A bstractIn a recent paper, Tye and Wong (TW) have argued that sphaleron-induced transitions in high-energy proton-proton collisions should be enhanced compared to previous calculations, based on a

Search for sphalerons: IceCube vs. LHC

A bstractWe discuss the observability of neutrino-induced sphaleron transitions in the IceCube detector, encouraged by a recent paper by Tye and Wong (TW), which argued on the basis of a Bloch wave



Semiclassical study of baryon and lepton number violation in high-energy electroweak collisions

We make use of a semiclassical method for calculating the suppression exponent for topology changing transitions in high-energy electroweak collisions. In the Standard Model these processes are

The sphaleron at finite mixing angle

The exact sphaleron solution in the bosonic sector of the electro-weak standard model is only known for weak mixing angle θw=0. To investigate the behaviour closer to the experimental value θWexp≈30°

An upper bound on the total cross-section for electroweak baryon number violation

An upper bound on the total cross-section of s-wave electroweak instanton/sphaleron induced baryon plus lepton number violating processes is presented. It is obtained by exploiting a recently

We review recent progress in the study of the anomalous baryon number non-conservation at high temperatures and in high energy collisions. Recent results on high temperature phase transitions are
