EPJ C Submission Guide: Scope, LaTeX Package, and Readiness

EPJ C is not a generic European physics journal. Its identity is particles and fields, spanning experimental and theoretical work in high-energy physics and connected areas. The fastest fit test is to remove the technique from your title and ask what scientific object remains. If the protagonist is a particle, field, collider or detector result, astroparticle phenomenon, fundamental interaction, gravitational or cosmological question within the journal's current scope, EPJ C may be plausible.

If the protagonist is condensed matter, atomic and molecular physics, soft matter, or another field served by a different EPJ title, the correct move is rerouting, not stretching the introduction. Read several recent EPJ C articles closest to your topic and compare the level of consequence, not merely shared keywords.

The official instructions specify LaTeX and ask for the original source, including style files and figures, plus a PDF of the compiled output. Treat reproducible compilation as part of submission quality.

Before upload, create a clean directory and test it outside your working environment. It should include:

• the main .tex file and any included source files;
• bibliography data or a complete bibliography in the source;
• every figure at the referenced filename and path;
• required class or style files not supplied by the standard template;
• a compiled PDF that matches the source exactly; and
• any supplementary files, clearly named and cited in the manuscript.

Remove unused drafts, duplicate figures, local absolute paths, and private notes. A source archive that only compiles with files elsewhere on your computer creates avoidable technical friction.

The title page should identify all authors, affiliations and addresses, and the corresponding author's email. Check the author order and institutional names against the portal before submission; inconsistencies become harder to resolve later.

EPJ C asks for a 150–250 word abstract. The official instructions advise avoiding undefined abbreviations, unspecified references, and mathematical expressions where possible. That is also a useful editorial discipline. A strong abstract moves through four jobs:

1. name the physics problem;
2. identify the method or evidence needed to interpret the result;
3. state the principal result with appropriate uncertainty; and
4. explain the consequence without extending beyond the analysis.

If the abstract needs several equations to communicate the contribution, test whether the result can be stated in physical language first. Keep essential technical qualifications, but do not make the editor decode notation before understanding the advance.

For theoretical work, list the assumptions that the main conclusion depends on and show where their domain of validity is established. For phenomenology, distinguish a robust prediction from a benchmark-dependent result. For experimental work, make the uncertainty model, controls, calibration, and statistical interpretation easy to locate. For data or software contributions, explain validation, accessibility, and reuse.

Then read the title, abstract, headline figure, and conclusion consecutively. The degree of certainty should remain stable. If the title says “evidence,” the abstract says “observation,” and the results support only “compatibility,” the package is not ready.

The official EPJ C instructions use numbered references in square brackets and require that the reference list contain works cited in the text that are published or accepted. Tables and figures should be numbered, cited in order, and understandable through their captions.

Do a claim-level reference check rather than a formatting-only pass. Verify that the cited work supports the specific sentence, that identifiers resolve, and that recent literature has not changed the comparison. For every figure, ask whether a reader can identify the variable, unit, uncertainty, sample or model, and comparison without guessing.

The paper is routed by method instead of physics. A manuscript may use collider data, lattice calculations, or a familiar high-energy tool without making a particles-and-fields contribution. Rewrite the one-sentence contribution without the method name. If the remaining question belongs to another EPJ title, reroute the paper. If it belongs in EPJ C, make that protagonist visible in the title and first two abstract sentences.

The headline hides a conditional result. A constraint, exclusion, or prediction can depend strongly on a benchmark, prior, model family, detector assumption, or perturbative regime. Put the condition beside the result rather than in a late limitations paragraph. Add a sensitivity figure or table that shows which parts survive plausible alternatives. EPJ C readers should not have to infer the domain of validity from scattered equations.

The source archive is not a publication artifact. Local paths, undeclared packages, stale figure versions, or bibliography files outside the archive can make an otherwise sound submission hard to process. Compile from a new directory or clean container, inspect the log, and compare the output with the intended PDF. Keep only files needed to reproduce that document.

The first figure and abstract answer different questions. This often happens when the analysis grew after the abstract was written. Mark the single result that earns the title. The first result figure should establish or directly motivate it, and the abstract should use the same comparison and certainty. Move interesting but secondary results later instead of giving several findings equal weight.

Example: from formal result to editorially legible claim

Suppose a paper derives a parameter constraint under several model assumptions. The weak version leads with the formalism, calls the bound “stringent,” and delays the comparison with existing limits. The stronger version states the physical question, names the data or theoretical input, gives the bound with its conditions, and explains which prior region or prediction changes. The detailed derivation remains essential, but the editor can now see why it belongs in EPJ C before evaluating every step.

The same discipline applies to experimental results. Lead with the observable and consequence, then make calibration, background modeling, uncertainty, and robustness easy to audit. Do not translate a local excess into “evidence” without the statistical and systematic support that word requires.

• Confirm the paper belongs in EPJ C rather than another EPJ or physics journal.
• Compare the contribution with recent EPJ C articles addressing the same problem.
• Keep the abstract within 150–250 words and define abbreviations.
• Reconcile title, abstract, first figure, and conclusion at the same certainty level.
• Verify author names, order, affiliations, and corresponding-author contact.
• Compile the manuscript from a clean copy of the source archive.
• Check every figure, table, reference, cross-reference, and appendix callout.
• Confirm originality, coauthor approval, and no simultaneous journal consideration.
• Read current portal prompts for declarations and data or code information before final submission.
